Simba SUPERROAM MAX QUALITY in AUSTRALIA

Hi guys! Gonna head to Australia soon for Exercise Trident after being done with Exercise Lancer about 1.5 months ago. Curious if anyone use Simba Superroam Max in Shoalwater Bay Military Training area and whether it is good?

Australia is listed as one of the countries under Simba Superroam Max Group A, but personal anecdotes on how it performs would be great, as the unit has told us that the preferred Telco over there is Telstra. Tried to look up Simba Website but couldn't find any information regarding this, so personal anecdotes will help a lot! Thank you in advance!
