A duplex in Hurstville works on the R2 side-street lots that clear the Georges River 600m2 minimum, while the CBD carries R3 and R4 density. This is the LGA's CBD and rail interchange, and the side streets hold Federation and inter-war character while R3 and R4 redevelopment runs around the CBD, so near the centre density is the higher use. On a qualifying R2 side-street lot a Torrens-title duplex can work.
The ground is predominantly Class M Wianamatta Shale, so footings get stable bearing and a slab off geotech is routine on both dwellings. Where a lot sits in the R3 or R4 CBD precinct a medium or high-density scheme may beat a duplex. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Hurstville block: whether it clears the 600m2 minimum, whether CBD density applies, and any heritage on the side streets. Those set the best use.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you the best use of it.

Side-street duplex, CBD density
This CBD suburb holds Federation and inter-war character on the side streets, with R3 and R4 redevelopment around the centre.
A side-street R2 lot clearing the Georges River 600m2 minimum suits a Torrens-title duplex, while near the CBD density is the higher use.
Stable ground
The Class M Wianamatta Shale gives footings stable bearing, so a slab off geotech is routine on both dwellings.
In the R3 or R4 CBD precinct density may beat a duplex, with older fibro stripped under licence first.
