What it be better to get LRGB and 5nm Ha Astrodon. I'll see how much the 3nm is in Australian dollars.
From reading, if I go with the 3nm I would need to get the N2 if I want to shoot in nitrogen. Is it worth getting N2 and what filter would it replace? As I will get a 7 Square filter wheel I will be limited in the number of NB filters, and I'll get the other filters as when I can afford them.

I would get the LRGB and 5nm Ha. I don't see any gain in getting 3nm Ha its more the 3nm O111. 5nm Ha gets both the Ha and the N11 so no need for a 3nm Ha which just requires longer exposure time to pick up a little bit more detail. I considered getting the 3nm at one point but Don recommended the 3nm for the O111 and if you look at his images he often uses the 5nm Ha and the 3nm O111.
I'd add the O111 later as most targets are LRGB or HaLRGB.
