Melbourne Victory slumped to their first loss of Australia's A-League season, and had a player sent off for the third consecutive game in a 2-0 loss to Queensland Roar here on Sunday.

Late goals from substitutes Tahj Minniecon and Michael Zullo sealed Roar's victory and ended a weekend when Victory and Sydney FC both lost their unbeaten starts after six rounds.

Minniecon broke the deadlock in the 83rd minute and Zullo scored in injury time, after Costa Rican midfielder Carlos Hernandez was sent off for two yellow card offences in the space of ten minutes in the second half.

It was the third straight match Melbourne finished with ten men, following a win over Adelaide United and a draw with Central Coast which also featured red cards.

The Victory and Sydney FC now share the top of the A-League after Sydney's shock 2-1 loss to lowly Wellington Phoenix in Wellington on Sunday. Both have the same goals for and against and goal difference.

Phoenix finally rediscovered their goalscoring form to record their first win of the season after Alex Brosque had put Sydney ahead in the 20th minute. Former AFC Wimbledon striker Shane Smeltz equalised just before half-time with a header at the near post, before Tim Brown got the winner in the 76th minute.

Adelaide United celebrated their midweek Asian Champions League quarter-final win over Japan's Kashima Antlers with a 2-0 win over champions Newcastle Jets at home on Saturday. Brazilian striker Cristiano claimed a second half double to give Adelaide all the points.

Central Coast Mariners had a convincing 4-1 home win over Perth Glory on Friday.
