Shopping for CBD oil in Melbourne means comparing bottles by concentration — and concentration is mg-per-mL, not the headline number on the label. Understanding CBD oil strengths is the first practical step: a bottle marked 1000mg sitting next to one marked 3000mg looks like a straightforward choice until you realise both may hold very different amounts of oil, which completely changes what you are comparing. This guide works through the conversion maths, maps it to the CBD Oil Melbourne range (with AUD prices), and explains what the other label details — spectrum, carrier, batch number — actually mean.
Why mg-per-mL matters more than the headline number
The number printed in large type on a CBD oil bottle is the total cannabidiol content of the entire bottle, not a per-serving or per-mL figure. Think of it the same way you read kilojoules on a food package: the headline is for the whole container, and the useful unit is per serving or per 100g. Every CBD oil label uses the same convention — total mg in the whole bottle.
If two bottles both say 1000mg but one holds 30ml and the other holds 50ml, the 30ml bottle is noticeably more concentrated: 33mg/mL versus 20mg/mL. Comparing them by their label alone overstates how similar they are.
The calculation you need is a single division: total mg ÷ total mL = mg per mL. That figure — milligrams per millilitre — is the only honest unit for comparing any two bottles from any two suppliers. Every other comparison is incomplete.
Spectrum and concentration are separate facts. A full-spectrum CBD oil and a broad-spectrum CBD oil at the same 1000mg / 50ml share an identical concentration of 20mg/mL. The spectrum label tells you about the THC content and cannabinoid profile, not the strength. Conflating the two is one of the most common label-reading mistakes.
What does 1000mg mean on a CBD oil bottle?
The entire 50ml bottle contains 1000mg of cannabidiol. Divide 1000 by 50 to get 20mg/mL. A 0.5ml dropper fill contains 10mg. The headline number describes the whole bottle, not any single serving.
Is a higher mg number always stronger?
Only when the bottle size is the same. A 3000mg oil in a 50ml bottle (60mg/mL) is stronger than a 3000mg oil in a 100ml bottle (30mg/mL). The only reliable comparison unit is mg per mL — always divide before comparing.
The conversion maths and mg/mL table
Every bottle in the CBD Oil Melbourne range holds 50ml of oil. That fixed volume makes the arithmetic simple and lets you compare directly across strengths and spectrum types.
| Label strength | Bottle volume | CBD per mL | Per 0.5ml dropper |
|---|---|---|---|
| 1000mg | 50ml | 20mg/mL | 10mg |
| 3000mg | 50ml | 60mg/mL | 30mg |
| 6000mg | 50ml | 120mg/mL | 60mg |
| 12000mg | 50ml | 240mg/mL | 120mg |
A standard dropper bulb draws roughly 0.5ml of oil. Multiply 0.5 by the mg/mL figure and you have the amount in a single dropper fill. The 3000mg bottle delivers three times the cannabidiol per dropper that the 1000mg does — in the same physical volume of oil.
This table also shows you why a 30ml bottle at 1000mg (33mg/mL) is stronger per drop than the CBD Oil Melbourne 50ml bottle at the same headline strength (20mg/mL). If you are comparing products from different suppliers, always do the division yourself; never assume equal bottles.
CBD Oil Melbourne CBD oil range: full-spectrum and broad-spectrum
CBD Oil Melbourne carries four strengths in two spectrum types — eight CBD oil products in total, all in 50ml MCT bottles, all imported from EU Labs and lab-tested by batch, with a Certificate of Analysis available on request.
Full-spectrum range — whole-plant hemp extract, legal trace THC (under 0.3%)
- CBD Oil 1000mg — Full Spectrum — $89.95 · 20mg/mL · 10mg per 0.5ml dropper
- CBD Oil 3000mg — Full Spectrum — $220.00 · 60mg/mL · 30mg per dropper
- CBD Oil 6000mg — Full Spectrum — $390.00 · 120mg/mL · 60mg per dropper
- CBD Oil 12000mg — Full Spectrum — $585.00 · 240mg/mL · 120mg per dropper
Broad-spectrum range — whole-plant hemp extract, THC removed entirely (0% THC)
- CBD Oil 1000mg — Broad Spectrum — $89.95 · 20mg/mL
- CBD Oil 3000mg — Broad Spectrum — $220.00 · 60mg/mL
- CBD Oil 6000mg — Broad Spectrum — $390.00 · 120mg/mL
- CBD Oil 12000mg — Broad Spectrum — $585.00 · 240mg/mL
Both ranges use MCT (coconut-derived) carrier oil, share the same 50ml format, and go through the same batch-testing process. The sole compositional difference is that full-spectrum retains a legal trace of THC; broad-spectrum does not. For Melbourne and wider Victoria customers, CBD Oil Melbourne ships all eight options Australia-wide.
CBG and CBN oils: a different cannabinoid, the same strength scale
Beyond the core CBD oil range, CBD Oil Melbourne stocks CBG oil (cannabigerol) and CBN oil (cannabinol isolate, THC-free) — each available at 1000mg, 3000mg, 6000mg and 12000mg in the same 50ml MCT format.
CBG and CBN are distinct cannabinoids found in the hemp plant, not variations of CBD. The mg/mL maths works identically: a CBG oil 3000mg bottle holds 60mg of cannabigerol per millilitre; a CBN oil 6000mg bottle holds 120mg of cannabinol per millilitre. If you are browsing the full product range, the same table above applies to every 50ml bottle regardless of which cannabinoid it contains.
What is CBG oil and how does its strength work?
CBG oil contains cannabigerol as its primary cannabinoid — a distinct compound from cannabidiol. The mg/mL calculation is identical: the CBG oil 3000mg bottle at 50ml holds 60mg of cannabigerol per millilitre. The same table in this guide applies to every 50ml bottle in the range, regardless of which cannabinoid it contains.
Comparing value: price per mg
Once you have the mg/mL figures, value comparison is equally straightforward. Divide the retail price by the total milligrams on the label to get the cost per mg:
| Strength | Price (AUD) | Cost per mg |
|---|---|---|
| 1000mg | $89.95 | $0.090/mg |
| 3000mg | $220.00 | $0.073/mg |
| 6000mg | $390.00 | $0.065/mg |
| 12000mg | $585.00 | $0.049/mg |
The cost-per-mg falls significantly as you move up the range. The 12000mg bottle costs just over half the per-mg price of the 1000mg entry option. For Melbourne buyers who plan to use CBD oil regularly over an extended period, the higher-strength formats can represent a meaningful saving over time — provided the concentration per dropper suits how the bottle's label directs you to use it.
From our CBD oil range
CBN Oil 3000mg Cannabinol – 50ml
Cannabinol (CBN) isolate, THC-free and more concentrated: 3000mg in 50ml of MCT oil at 60mg per ml — the cannabinoid that develops as hemp ages, often chosen for evening use.
Pet CBD Oil 2000mg Full Spectrum – 50ml
Pet-formulated full-spectrum CBD: the same hemp source as our human range in a neutral MCT carrier, 2000mg in 50ml at 40mg per ml, trace THC under 0.3%, with no human-targeted flavours. Best introduced with your vet.
CBD Oil 1000mg Full Spectrum – 50ml
Whole-plant full-spectrum CBD: 1000mg of cannabidiol with the hemp plant's minor cannabinoids and terpenes, 50ml of MCT oil at 20mg per ml, a legal trace of THC under 0.3%.
Spectrum choice: full-spectrum vs broad-spectrum
The full-spectrum vs broad-spectrum decision sits alongside strength as the second major label variable. Both products start from the same whole-plant hemp extract. The difference is a single processing step: broad-spectrum goes through an additional stage that removes the THC fraction entirely.
In compositional terms:
- Full-spectrum: CBD + minor cannabinoids + terpenes + legal trace THC (under 0.3%) — the full plant profile as extracted.
- Broad-spectrum: CBD + minor cannabinoids + terpenes — THC removed, 0% THC on the label.
Neither type has any health-claim advantage over the other. This is a composition preference: whether you want the trace THC present or removed. When comparing CBD oil strengths across suppliers, the spectrum type is a separate variable to the mg/mL figure — check both independently. For the complete picture on what these terms mean on the label, the full-spectrum CBD oil guide and the broad-spectrum CBD oil guide cover each in detail.
What is the difference between full-spectrum and broad-spectrum CBD oil?
Both are derived from whole-plant hemp. Full-spectrum retains a legal trace of THC (under 0.3%); broad-spectrum has THC removed to 0%. The CBD content, the MCT carrier, the 50ml volume and the lab-testing process are identical across both types.
Reading the label's serving guide
Every CBD Oil Melbourne bottle carries a suggested serving printed directly on the label — typically expressed as a dropper volume (0.25ml or 0.5ml) and a frequency. That figure is the starting reference for an adult consumer. It is not a medical recommendation; it is the manufacturer's product-use guidance, the same way a supplement label states a daily serving.
The standard industry starting approach is to begin at the smallest serving indicated and hold it consistent for several days before considering any change. The dropper itself makes serving size practical to measure: squeeze the rubber bulb, submerge the glass tube in the oil, release the bulb until the oil column reaches the 0.5ml graduation mark. The guide to using CBD oil on this site walks through dropper technique and storage in plain terms.
For guidance that goes beyond what a CBD oil label can offer — including whether a particular strength or serving size is suitable for your circumstances — a GP or pharmacist with experience in cannabinoid products is the appropriate contact. No online guide on CBD oil strengths, including this one, can responsibly substitute for that conversation.
COA and batch verification
A Certificate of Analysis (COA) is a third-party laboratory report confirming the actual composition of a product batch — cannabinoid levels, THC content, and the absence of contaminants. It is the document that makes label claims verifiable rather than assumed.
All CBD Oil Melbourne products are third-party lab-tested by batch. If you want the COA for a specific bottle you have purchased — or before you purchase — contact the store at [email protected] with the batch number printed on the base of the bottle. Reputable CBD suppliers make COAs available on request without hesitation; if a supplier cannot or will not provide one, treat that as a transparency gap worth noting.
Is there a COA for each bottle?
Yes. All CBD Oil Melbourne products are third-party lab-tested by batch. Email [email protected] with your bottle's batch number to request the COA for that specific batch.
Is CBD oil legal in Victoria?
CBD oil for human use is regulated by the Therapeutic Goods Administration (TGA) — the Australian government body responsible for therapeutic goods. The relevant framework applies identically in Victoria as in every other state:
- Prescription CBD (medicinal cannabis) is accessible via an authorised prescriber or the TGA's Special Access Scheme.
- Low-dose CBD was rescheduled in 2021 to permit pharmacist-access without prescription at certain concentrations; this pathway has seen limited uptake in practice.
- CBD oil imported online from overseas without a valid Australian import permit does not comply with TGA rules.
The TGA website is the primary reference for current scheduling and regulatory status. For questions about any specific CBD oil product's compliance, a pharmacist is the right first contact.
