I use to run it in my Clio Sport and only ever got an increase of 1 PSI on a stinking hot day after some hard driving.
Where can I find a nitrogen pump in Sydney? How much for a fill / top-up?

Used to use nitrogen when overseas - one time cost when replacing the tyre and free top-ups for life... tyres ran cooler with more stable and consistent pressure...
