My personnel opinion is that if you don’t already have a strata go for a Torrens Title instead.
Torrens Title
Torrens title land division is the division of land into at least two allotments, which are held independently of one another. There are generally no shared facilities or infrastructure.
As far as I can tell this gives you 2 totally separate titles and no common property, so no need for sinking funds, admin funds, AGM, voting etc. Seems to me a much simpler system.
You really need to speak to a specialist regarding the best way forward and their are some on here. Just read their entries and see which one knows their stuff best.
