A bit difficult to calculate but here are the liquidity rules:

S&P/ASX 300. Stocks require a minimum Relative Liquidity of 30% for inclusion in the S&P/ASX 300.



where:
• Stock Median Liquidity is the median daily value traded on the ASX for each stock divided by the average float/index weight-adjusted market capitalization for the previous six months and;
• Market Liquidity is determined using the market capitalization weighted average of the stock median liquidities of the 500 companies in the All Ordinaries index. The market capitalization weight for stocks in the S&P/ASX 300 is float-adjusted, otherwise the unadjusted market capitalization is used for weighting purposes (i.e. an IWF of 1 for stocks in the All Ordinaries, but not the S&P/ASX 300).
