Don't forget the 10% cashback from Shopback, which will reduce the price down to ~$263.65 (cashback ex. gst). A search reveals that's the cheapest price on this site, so it's likely the historical low.
I also believe it's the Australian version so it should have dual sims - not quite sure on Band 28 though.
the australian version definitely has band 28 and nfc.
only downside is 440 processor which is still ok for most people not into heavy gaming and just running browser, apps and normal phone functions, and oreo let’s you load apps into the memory card.
other option for australian stock, band 28 and nfc would cost more, nokia 6.1 from officeworks $317, nokia 7 plus from jb for $399., bothie nokia’s are on pie alteady but australian versions are single sim.
