The defending premiers met fellow undefeated side Orana Spurs 1 on Sunday and the Bulls ensured it was they who kept their perfect record intact courtesy of a 4-1 win.

Captain-coach Scott Fox and his men have now won four-from-four this season and their attack has been particularly impressive with more than 30 goals scored already in 2015.

Spurs 1 now drop back to fourth on the ladder following the loss.

Despite their imposing form, the Bulls 1 team is not alone at the top of the ladder after Macquarie United 2 kept their own unbeaten run going.

United 2 proved too strong for the Bulls' other side, Dubbo FC 2, and won 3-1.

The two front runners don't meet each other until round 10 on July 5, meaning the opportunity for an extended winning streak is in front of them.

Macquarie United 1 are hot on the heels of the top two and returned to form on Sunday with a 3-2 win over Westside.

After only forming last season, Macquarie United will be delighted the club has started the season as it has with two sides currently inside the top three.

United 1 will have the perfect chance to see how they're travelling next week when they go up against the rampant Dubbo FC 1.

In other matches in round four, EDU were the big winners of the weekend as they brushed aside Newtown 11-0.

After losing their first two matches EDU have bounced back with two big wins, keeping a clean sheet in both.

EDU now head into this weekend's match against Orana Spurs 2 full of confidence.

The Spurs 2 team will also head into that game on the back of a win after they defeated South Dubbo Wanderers 2-1.

In the final match, the South Dubbo Wanderers 2 side made the trip to Wellington and returned home with a share of the spoils after a 2-2 draw.
