Starhub Data Roaming No Longer Usable in Australia?

I had been using Starhub card in Sydney by choosing Vodaphone (choosing connecting to Telstra would result in no data connection and optus no longer accept Starhub customers). The data is metered by the same rate as they would in Singapore.

This month I was back in Sydney and non of the three provided data anymore. Does anyone have recent experiences using starhub global data roaming in Australia?

I'm thinking this may be related to vodaphone's withdraw from 3G. Starhub probably didn't have a 4G roaming contract with the Aussie providers. My phone shows LTE connections in Singapore so it wasn't because I used an old SIM card with no 4g support
