The ever-reliable Lolley broke through the stalemate at Allianz Stadium in the 52nd minute before launching himself to the top of the league's golden-boot standings with his 68th-minute penalty conversion on Wednesday.
With a brace not enough, Lolley completed his hat-trick in the 88th minute after picking up the crumbs of Patryk Klimala's unsuccessful goal attempt.
The Englishman first hit the scoreboard with a volley thanks to an assist from Anthony Caceres, before adding his second when Glory defender Andriano Lebib handballed inside the box.
Lebib's arms made contact with the ball after diving in a desperate attempt to stop Klimala from collecting Lolley's pass in the 67th minute.
Lolley would have notched an assist after another pass helped Klimala find the back of the net in the 80th minute, but his Polish teammate was ruled offside.
He now leads the league with eight goals, ahead of Wellington's Kosta Barbarouses and Western Sydney's Nicolas Milanovic with six.
In Sydney's last two matches, the 32-year-old scored a brace to help secure a 3-0 win over Melbourne Victory before kicking a crucial goal in their 2-2 draw with Newcastle.
His efforts helped the Sky Blues leapfrog bitter-rivals Western Sydney to seventh on the ladder and take their undefeated streak to four matches.
On 17 points, they are one point off sixth-placed Western United.
Perth have now lost three straight games and sit 12th on the table with just one win.
Their rebuild campaign under David Zdrilic won't get any easier as they face league-leaders Auckland FC at home in their next fixture.
A possible injury to captain Adam Taggart could only compound second-from-bottom Perth's woes.
Taggart was unexpectedly substituted out of the match at half-time and appeared to have picked up a quad injury.
Sydney dominated the first half and should have taken the lead a minute into added time when Joel King sent a curling pass towards goal and lured goalkeeper Oliver Sail off his line.
Sail attempted to punch the ball clear but it instead came off the back of his gloves and landed at the feet of Sydney midfielder Caceres.
Caceres toe-poked the ball but luckily for Sail, Glory teammate Lebib was quick on his feet to deny the hosts on the line.
The Sky Blues had another glimpse earlier in the half when Perth midfielder Nicholas Pennington gave away a free kick on the edge of the box for a foul on Anas Ouahim.
Lolley took the kick in the 29th minute and beat the wall of Glory defenders, but Sail pulled off a superb save to deny the in-form striker.
The visitors had only two shots at goal in the first half but almost drew first blood.
Sydney keeper Harrison Devenish-Meares had fumbled Josh Risdon's goal attempt at first touch and had to scramble to keep Taggart from pouncing in the 16th minute.
