Using a trust structure and Land tax in Australia

Hi
Im just starting out on my investment journey and looking for some advice/ understanding on Land tax in Trusts.
Im buying properties that are positively geared, So i decided to setup a family trust structure.

My current holdings
My name : my home, and 1 investment property that is very negatively geared ( and has a $4000 land tax bill)
Family Trust : 2 properties valued around 300k each – recently purchased both positively geared.

My understanding
My personal properties pay land tax on their holdings, and my trust then pays land tax on its own holdings.

I have heard of people setting up a trust for each property, or holding at most two properties per trust to lower the land tax, as there is basically a 300k tax free threshold ? is this correct ?
Is it worth setting up a trust for each property if the property values are low around the 300k mark, Or how does it work ?

Trying to plan my strategy before buying any more property.
