Capital sent a couple over the bar before, WaiBOP's Leanna Ryan burst into the box, in the 40th minute, and was tripped for an obvious penalty.
Serena Murrihy confidently stepped up to tuck home the go-ahead goal for the hosts.
WaiBOP had the better of the early stages of the second half but the visitors got back on level terms with 20 minutes left. Katie Barrott got the last touch after a defensive mix up from the home team.
The game opened right up after the goal as both sides hunted for a winner. WaiBOP came close through both Kim Maguire and Theresa Rhein, while Capital had a late free kick well saved by Georgia Candy.
In the end, both sides had to settle for a point which seemed a fair enough result.
