Hi. Just wondering when Optus is planning to close the 3G network please? (i.e. When will it become necessary for me to upgrade from my current Optus 3G mobile phone to a 4G mobile phone?)

I doubt there's a firm date in mind yet. Rest assured you will get several years of official notice.
As a guide each 'G' is introduced aproximately every 10 years (2G 1990, 3G 2000, 4G 2010, 5G 2020)
2G was around for 25 years before being switched off. That would put 3Gs End Of Life at around 2025.
Bear in mind though that 3G was a considerable step up from 2G and may last longer again.
