Mokela hooked the kick badly to the left, with the miss ensuring for a share of the spoils.

A tackle-busting run by Force winger Brooklyn Teki Joyce set up Anneka Stephens for the home side's first.

A yellow card to Smith two minutes later changed the complexion of the match.
Brumbies winger Biola Dawa scored while the Force were down a player.
And when Brumbies flanker Chioma Enyi scored two tries in the space of three minutes approaching half-time, the visitors were in complete control.
