It was a supremely impressive performance by Subiaco who did welcome back experienced pair Jordan Lockyer and Chris Phelan, but also continued to blood youngsters with Ethan Burnett becoming another early season debutant and looking the part kicking a goal.
Once again Subiaco's forward-line showed that it has plenty of firepower left even with losing Liam Ryan and Liam Baker in 2018, and with Clancy Wheeler out injured.
Ben Sokol had another starring performance after a strong battle with former South Fremantle teammate Steve Verrier for three quarters. He finished with 19 possessions, nine marks, five tackles and five goals against his old side.
Rhys Waters backed up his five goals from Round 1 booting another two majors as did Kyle Halligan, Brad Stevenson and ruckman Zac Clarke to go with his 13 touches, four tackles and 32 hit outs.
The Subiaco back-line was also superb against the potent South Fremantle forward-line that included Ben Saunders, Blaine Johnson, Mason Shaw and Matt Parker.
Angus Litherland was tremendous on Saunders holding him to three kicks and one goal while Hayden Kennedy finished with 21 possessions and eight marks and Aaron Heal 18 disposals and five marks.
Then it was Josh Deluca and Kyal Horsley who were dominant forces through the midfield for the Lions. Deluca finished with 33 possessions, six marks, five inside 50s and a goal while captain Horsley had 31 disposals, six tackles, four marks and a superb goal from 50 after winning a one-on-one contest.
Lachlan Delahunty had another strong showing too splitting his time between playing up forward and the ruck, ending up with 24 possessions, 18 hit outs, seven marks and six tackles.
It was a tough first up game to open the season for South Fremantle following the Round 1 bye and up against a strong Subiaco unit who has made the past four WAFL Grand Finals and had beaten East Perth by 118 points a week earlier.
South Fremantle was close to full strength, though, with the only change of significance from 2017 being the departure of Tim Kelly to Geelong but the Bulldogs did welcome Nick Suban on the back of 156 AFL games with Fremantle along with playing in three WAFL premierships.
The Bulldogs were missing the suspended Cory Dell'Olio, injured Adam McIntosh and unwell Zac Strom but it provided the opportunity for Noah Strom to make his debut on the back of 29 colts and 58 reserves appearances.
South Fremantle's star-studded forward-line couldn’t quite get going against the powerful Subiaco defence. Despite 47 inside-50 entries, the Bulldogs managed just the nine goals with Blaine Johnson the only multiple goal scorer with two.
Ben Saunders managed just three kicks, Tom Vandeleur three, Mason Shaw five and Matthew Parker 10.
Reigning Sandover and Hughes Medallist Haiden Schloithe battled hard in the middle for South Fremantle with 26 possessions, five tackles and a goal with Shane Hockey adding 21 touches and five tackles, and Nick Suban 18 disposals and five inside 50s.
Veterans Ryan Cook (18 touches, seven inside 50s) and Ashton Hams (18 possessions, six marks) battled hard while ruckman Brock Higgins was outstanding with 18 disposals, 30 hit outs and six inside-50 entries.
The Bulldogs back-line were overwhelmed in the end by the Lions in the 58-point defeat but debutant Noah Strom and seven-gamer Chad Pearson held up well. Blayne Wilson did well also limiting Brad Stevenson to two goals after he kicked seven the previous week.
Meanwhile, in the reserves clash at Fremantle Community Bank Oval, South Fremantle ended up storming home to win a thriller against Subiaco 9.7 (61) to 8.11 (59).
The Bulldogs started strongly with four goals to one in the first quarter but by half-time the Lions had assumed the lead by eight points. Subiaco extended its advantage to 25 points by three quarter-time.
But South Fremantle held Subiaco scoreless in the last term and kicked 4.3 to claim the two-point win.
Andre Coutinho kicked two goals for South Fremantle while Brandon Donaldson gathered 22 possessions, Jake Florenca 22, Josh Collard 19, Coutinho 19, Zac Dent 18 and Trent Reed 17 to go with 10 tackles and a goal.
Ruckman Jake Solomon had 62 hit outs to go with 10 possessions.
Ryan Mu kicked three goals for Subiaco's reserves and Mckenzie Lawrence two while Daniel Leach gathered 28 disposals, Michael Braut 23, Craig Hoskins 21, Bailey Matera 19 and defender Ben Reid 17.
