I  posted a link in another post re Diesel Heaters for Caravans.

This link is to the same company.  Aliexpress Australia,

The particular webpage refers to the latest way to monitor tyre pressures on your Dash display.This one is for the Nissan XTrail. Uses an OBD plugged into the car port.  Other modern vehicles are on the list now.

If you type in tyre monitor it will give you LOTS of different versions and prices.

You can then check out Ebay etc and see what's in Australia.

As I said in my other post it's a waiting game with the site can be three weeks or so.

Just one option to check out.

Hope you find what suits.

G`day Bill,
Have a look at the Safety Dave website . I use their TPMS . It monitors each tyre individually and gives you a rolling read out the pressure and temperature of each tyre .
Cheers ,
