I guided 2secs with my G11 at 2m FL plus, the mount is hard pressed to handle faster corrections let alone chasing seeing. If you use 1 sec to good effect, then perhaps the seeing at Wiruna is better than sydney (likely). Anyway, if it works, why not ;-).
With an OAG though, 1 sec exposures maybe harder to achieve, given the reduced chance of a suitable bright guide star.
