Constant rain in Redcliffe had prompted doubts that the game would go ahead but Brisbane probably had no choice, with 10 games still to play in their regular season.
At times for the players it was like running in snow, while passing in a sand pit, though both teams did well in the circumstances, which improved marginally after halftime.
Steven Taylor and Tim Payne were rock solid at the back under constant pressure, while it was particularly tough for the midfielders. David Ball performed his usual lung-busting role while Ulises Davila was superb in the second half, carving the Brisbane defence open at will, with his wonderful creativity, though the state of the field hampered Wellington's possession-based game.
The Roar have the stingiest defence in the A-League and were always going to be hard to break down, but the Phoenix dominated the last half hour, only missing the final flourish.
The result means the Phoenix remain in eighth place, a point behind Brisbane, who have three games in hand.
There were few genuine opportunities in the first half. Louis Fenton flung over some crosses, while Davila was blocked by a teammate when the ball fell in the area. More than 30 minutes passed before the first shot on target - covered well by Oli Sail – partly because each corner zones of the pitch were the worst.
Tomer Hemed and Ben Waine barely saw the ball, while Brisbane had 12 unanswered shots in the last 30 minutes of the half, though most were ineffectual. Their best chance was foiled by a timely lunge from Clayton Lewis, after the ball fell to Jack Hingert six yards out.
Fenton accrued a harsh yellow card after falling in the area and will miss the next match, along with Cameron Devlin who was also booked.
After defending too deep in the first half, the Phoenix were more compact and were able play more football, with Davila somehow finding space and time to torment the home defence. He helped to carve out a series of half chances to Fenton, Ball and substitute Jaushua Sotirio, whose pace helped to change the complexion of the match.
The Australian had the best opportunities, but couldn't keep his feet in the crucial moments, twice falling in the area, while Reno Piscopo stung the palms of Roar keeper Jamie Young with a long-range drive.
