I've tried using numerous Optus resellers, and Catch is by far the worst.
I'm guessing their auth server is slow as hell, because after periods of inactivity it takes a long time to reconnect / start receiving data again.
Called their tech support and they couldn't provide me with a fix.
Something to be aware of if you're shopping for a new plan.
