The Mariners followed up a 4-2 opening-round away victory over Brisbane with a crushing 5-1 home demolition of Canberra United on Saturday.
The attacking trio of Peta Trimis, Talia Kapetanellis and Skye Halmarick tormented the visiting rearguard, with Danika Matos another creative force.
Elsewhere, Western Sydney came from behind to score a 3-1 home win over Brisbane, before Adelaide United and Perth played out their first ALW goalless draw.
In Gosford, the rampaging Mariners scored twice in the first half and three times in the second, before Canberra netted a late consolation.
Teenager Halmarick slotted home a Matos cross in the sixth minute and just after the half hour Central Coast doubled their lead when Kapetanellis headed in a Trimis cross from a similarly close range.
There was more misery after the break for Canberra, who were playing their first game of the season after an opening-round bye.
Te Reremoana Walker marked her first ALW start in four years by scoring after a goalmouth scramble and the irrepressible Kapetanellis finished off another good Trimis cross for the fourth.
Substitute Alexia Karrys-Stahl shrugged off two defenders and fired in the fifth, with Sienna Dale pulling one back for the visitors near the end.
"In that game it all gelled and we didn't stop the whole 90 minutes, it was just so entertaining," Kapetanellis told Paramount Plus.
In Parramatta, both sides scored from set pieces in the first 15 minutes, with the Wanderers adding two more goals in the second half.
Sofia Sakalis inadvertently beat her own goalkeeper, before her Western Sydney teammate Sofia Palywoda equalised with a firm header from another corner.
Talented 17-year-old Talia Younis gave the Wanderers the lead with a well-taken penalty following a push by Annabel Martin on Sakalis.
Lively American forward Brooke Miller scored a third with a cracking finish, after going close with four previous attempts.
In Adelaide, both teams struggled to create good chances with just a single shot on target between them in the first half and five for the match.
United's Melissa Taranto, Chelsie Dawber and Isabella Yakel each had a shot saved by Perth goalkeeper Alyssa Dall'Oste in the second half.
The Glory's only shot on target wasn't until the 76th minute, but they held firm to earn four points from their first two games away from home, keeping a clean sheet in both.
