I'm not sure why that would happen. I would have suggested a roaming bar, however, if the phone works in Singapore et al. it's obviously not that.
My only suggestion would be to contact customer services and ask to speak to a Guru and see if they have an answer. https://www.o2.co.uk/contactus
Personally I have never come across a 'forbidden network' anywhere abroad?
You may need to try a new sim?
Edited to add, I have just found this answer on the EE forum. A similar question about Forbidden networks.

Have you changed sim cards at all since your last trip to Australia?
Forbidden network usually happens when you have selected 'preferred network' either in the UK or another country which then locks the network to the sim card. I think you may have to change the sim card which will then release the lock and allow other networks. Have a look in the settings to see if you have a 'preferred network' option which you can untick/switch off.
