I'll lend a hand with your concern about not being able to connect with Bankwest, ChrisSumn.
Are you receiving a specific error message when attempting to connect your bank? Any additional details will ensure a timely solution.
In the meantime, you can manually upload your bank transactions to QBO: Import bank transactions using a CSV file. This way, you can easily categorize them and then reconcile your account.
You can always get back to us if you need help doing a task in QBO. The Community is here to help.
