Powerdive or similar hookah hire

 Was dead keen to hire a Powerdive for an upcoming weekend at Rotto but Powerdive in Mosman Park no longer hire them. Anyone know any other places could hire one or a similar device to float along surface?

Not so keen on lugging several scuba kits over for shallow 5m dives. (tried free diving last years trip)

Any tips would be appreciated. Unable to justify the purchase of one as will not get enough use.
