We set up bank & mortgage with Westpac & got cards the same day, they've been great, a lot better than the UK.
If you can wait a bit before buying it would be wise, we bought & moved in after a month of being here & have been very lucky with what we got, now I know what horrors we could have been left with, I put ours down to 'It was meant to happen' but it frightens me when I think how little we knew, for us it worked but for so many it doesn't so I wouldn't suggest rushing too much
