Australia - Best 4G Internet Service?

Greetings Tek Family,

Long time channel subscriber, first time poster. Best 4G Internet Service? (in Queensland)

I will be looking into moving in with my partner and to my dismay (after some research) found that her place does not support ADSL2+ and have not been able to find any confirmation dates of any NBN rollouts in the area.

My solution to this problem was to mount a MIMO 700mhz-2700mhz antenna to the roof of the house to receive the strongest signal possible. I am confident that this solution will deliver the speeds I am looking for, but the issue is now finding a 4G provider/service that has a realistic data plan.

Living in Brisbane, I was hopeful when I found out that Vivid Wireless offered an unlimited monthly data allowance but then found I well outside their coverage zone. If I had to have a data cap, I could get by with 40GB a month but would prefer 50-70gb if possible as I would dedicate this connection to gaming, streaming and downloads.

Does anyone know of any service that could offer data caps (at a reasonable price)? I am willing to mess about with sims, prepaid solutions etc. if necessary.

This is the best deal I have found to date; 50gb a month for $140 on a 24 month contract through Vodaphone.

Be aware that if you are going to be doing a lot of gaming - the 4g networks have terrible latency. for most mmo's you should be ok, but twitch based shooters you will suffer.

What is your postcode/suburb?

4130 will be the postcode I will reside in.
