A scintillating Joel Rintala has scored four goals as Brisbane moved to the Hockey One summit with a 5-1 thrashing of Adelaide.
NSW kept pace with the leaders but trail on goal difference after beating Tassie 4-2, while Canberra won their first match of the season after a dramatic 3-1 penalty shootout victory following a 3-3 regulation-time draw in the league's third round on Sunday.
Brisbane were ruthless, going ahead when Kookaburras defender Corey Weyer scored off the fifth-minute penalty corner before Rintala doubled their advantage five minutes later.
Adelaide striker Isaac Farmilo pulled one back with a 29th-minute strike, which could have made his debut a match to remember.
But rampant Rintala ensured it was one to forget for the Fire by scoring from penalty corners in first-half stoppage time, and again in the 45th and 58th minutes to put the result beyond doubt.
Australia forward Blake Govers shone in Sydney, scoring all four of NSW's goals in their victory over the Tigers.
Govers put the Pride up from a penalty corner in the fifth minute before Sam McCambridge hit back in the ninth minute, and Kookaburras veteran Eddie Ockenden scored four minutes later to give Tassie a 2-1 lead.
But Govers struck in the 25th minute and added another in the 29th to edge NSW ahead.
The forward added his fourth at the end of the third quarter to seal the hosts' victory.
In Perth, cellar dwellers Canberra pulled off a stunning win over the Thundersticks to claim their first points of the season.
Tim Geers and Brayden King gave Perth an early 2-0 lead, but Goulburn local Jack Staines' quick-fire double levelled the scores at 2-2 by halftime.
Kookaburras forward Tom Wickham struck three minutes from fulltime, but Staines' brother Ben scored an equaliser a minute later to push the match to a shootout.
Canberra goalkeeper Andrew Charter then proved the hero by saving three of four penalty attempts to hand the Chill a 3-1 victory.
