Hi,
many Australian customers of yours use eWay for payment gateway and most I think would prefer to use the redirect option which is currently unsupported. Redirect removes the requirement for the server with joomla to be PCI-DSS compliant.
We want to use both Membership Pro and Event Booking but have not gone ahead because of this. I'm wondering if you have plans to develop a redirect payment modules for eWay? I'm sure others would also like to make use of it.
At the moment, I am too busy and could not work on it. I want to finish new version of Events Booking first. I will try to look at this payment plugin and implement it sometime next month
