Baldivis held off South Mandurah to claim an enthralling win as the Peel Football and Netball League Women's returned to action over the weekend.
Trailing by eight points with just minutes remaining in the final quarter, Falcon Renee Hardie slotted her second goal of the day to bring her side within two.
But the Brumbies stood tall in defence of their lead, fending off the challenge and scoring the final point of the game to finish 6.8 (44) to 7.5 (47) victors at Falcon Oval.
Best afield Sarah Rhodes led the way for the visitors, but it was the home side with the momentum early in the match.
Skipper Van Peer was on fire around the ground early and rewarded herself with the first quarter's only goal, giving the Falcons the early lead.
It took the Brumbies just two minutes to return serve when Miami Brotherton kicked truly early in the second, but some solid transition from the back half led by Hannah Davis gave the Falcons more opportunity.
Anyssa Hardy looked dangerous up forward for the hosts, but it was Savannah Hannakampf scoring the next to maintain their lead at the long break.
The third term was all Baldivis, though, as they turned the tide with five goals to Souths' two.
Skye Roberts booted two for the quarter while Alanna Impson imposed herself on the game.
Trailing by 10 points heading into the final term the Falcons conjured their response through Hardie, bringing them within a straight kick.
But Chloe Owen replied for Baldivis, kicking a major that would give her side just enough to hang on.
Hardie's second for the quarter made it interesting, but the Brumbies clung to victory in the end.
Pinjarra def. Rockingham
Things weren't so close when the Tigers hosted Rockingham at Sir Ross McLarty Oval on Friday night, with the reigning premiers stamping their authority on the competition early.
Five goals from superstar Jena Daniel proved the catalyst for the home side, as she drove her team to a 9.6 (60) to 0.2 (2) drubbing of the Rams.
The visitors were able to absorb the damage early with Kalani Ingram proving important, but unable to score themselves Rockingham went into half time trailing by 14 points.
From there Ailigh Coldstream and Brittany Fabry moved the needle for the Tigers, as they blew the Rams away.
Daniel scored three of her five goals in the second-half blitz, proving too much for the Rockingham defenders to handle.
The win sees Pinjarra rocket out of the gates ahead of their grand final rematch against South Mandurah next week.
Secret Harbour def. Dwellingup
Competition newcomers Secret Harbour made a statement in their first game of the season with an 11.6 (72) to 0.1 (1) win over the Dwellingup Razorbacks.
Isla Smith led the way as the Dockers women blasted their way to a huge round one victory.
Secret Harbour made a fast start and continued to pile on the goals, while a stout defence left Dwellingup without a goal for the entire four quarters.
Smith got the nod as best afield, while Chloe Bilston and Rosalia Cooper also impressed for the Dockers in the side's PFNL Women's debut.
The win sends them immediately to the top of the table, ahead of a round two date with Rockingham.
