The Southport School defeated Brisbane Grammar School 26-17 in a close encounter at Northgate in Round 6 of the GPS 1st XV competition.
It was one way traffic in the first half with TSS scoring all of the points with three converted tries.
Winger Mason King and fullback Keahn Skipps both crossed as captain Jye Gray raced away for a 90-metre runaway try just before half time, with flyhalf Spencer Alcock kicking three-from-three.
However, it was a different story in the second half as Grammar opened the scoring with hooker Nick Hatzipetrou crashing over first after the break.
Grammar scored the next two tries with winger Lewis Strachan and replacement Angus Tolhurst both diving over in the right corner to reduce the margin to four points at 21-17.
TSS received two yellow cards in the second half due to high tackles and poor discipline and Grammar capitalised.
Returning a kick, TSS captain Gray used his speed to burst through the Grammar defensive line, breaking four tackles before passing it out to Mason King for his second try of the game in the 62nd minute.

Terrace responded immediately after with Nicholas Dunstan going over for their first five-pointer of the game.
Ipswich’s centre pairing of Stanley Huen and Israel Leota were once again standouts, with both players making multiple line breaks using their speed and power throughout the game.
