As Hurdity says, it is very difficult to compare doses of progestogen with each other, because they all works slightly differently and the amount you have to take to get an effective dose through the liver varies.
It is also really difficult to compare across preparations as HRT and BCP and others tend to use different progestogens.
Norithisterone and levenorgestrel are useful as they are both widely used. I came up with:
COC is the highest by far. The progestogen, along with the oestrogen makes your body think that it has already ovulated from day 7, so it stops the production of FSH and oestrogen etc.
HRT is the next highest - this regulates uterus lining
POP is fairly low - it makes changes to the lining/cervix etc which make it unfavourable to sperm and pregnancy but does not stop ovulation and you tend to have fairly normal periods.
Newer POP like cerazette and other generic versions are higher dose which gives a longer window to take it, and sometimes prevent ovulation as well. They are a different type of progestogen from other preparations so it is very difficult to compare. I have seen in some places that it contains equivalent progestogen as in HRT, but there is no licence for this (in the UK - not sure about OZ) - only for contraceptive purposes. (On their own they can stop periods, or result in irregular or constant bleeding)
