Port Adelaide's fifth-straight win has them on the verge of their first AFLW finals series as injury further soured another tough day for Gold Coast.
Suns star Daisy D'Arcy will go for scans after hurting her right knee in Port's emphatic 8.10 (58) to 3.6 (24) win on the Gold Coast.
A lot would have to go wrong for seventh-placed Port to drop out of the top eight with one round left before the finals.
They host GWS next Sunday, and the 16th-placed Giants have lost their past seven matches.
In her AFLW debut, Power forward and former triathlete Jo Miller kicked the first and last goals of Saturday's game.
Port played as Yartapuulti for Indigenous round and Gemma Houghton marked the occasion by also kicking two goals.
At one point in her 70th game, the Indigenous star had kicked 70 goals and 70 behinds.
In humid conditions, Port's Abbey Dowrick racked up a team-high 23 disposals and gained 551m, as well as kicking a goal.
Niamh McLaughlin starred for the Suns, also with 23 disposals, while teammate Charlie Rowbottom had a game-high 25 possessions and 12 tackles.
The Suns' dirty day was summed up when Taya Oliver marked deep in a pocket. Rather than have a low-percentage shot at goal, they did the right thing and centred a pass to Claudia Whitfort - just as the final siren sounded.
D'Arcy had made a bright start to her 50th game, racking up 13 possessions.
But late in the second term she tried to avoid a tackle from Amelie Borg and her right knee buckled. The immediate fear is she has a torn ACL.
When Ella Maurer kicked Gold Coast's first goal at the start of the second term, the Suns had the lead.
But Port veteran Kirsty Lamb marked her 75th game a few minutes later by snapping a goal and the Power steadily kicked away, outscoring the home side in each quarter.
