Firstly, CGT is a Federal Tax and Land tax is a state based, so the rules on how each is applied are different. Therefore, just because you may claim a specific property as your PPOR but rent it out and therefore technically eligible for CGT free sale, has no relevance for how the property is treated for Land tax.
I believe the SA date for Land tax calculation is at midnight on June 30th. There are exemptions available, however, if I am assuming this is a standard rental agreement, your property's site value would be included in the calculation for land tax.
