The weekend was tipped to be season-defining for many of our Socceroos stars, with several players standing up to help their side record monumental victories.
Tom Rogic shook off an injury concern to produce a player-of-the-match performance in the Old Firm Derby, with Celtic now on course to top the Scottish Premiership once again.
Meanwhile, Denis Genreau has taken another huge step towards promotion to France's first division this weekend, with another stellar display at the heart of Toulouse's midfield.
England & Scotland
Tom Rogic has made an outstanding return from injury to become the hero once again for Celtic, as they came from behind to claim a famous victory against archrivals Rangers.
Despite an injury cloud hanging over the midfielder, after missing out on Australia's recent FIFA World Cup qualifiers, Rogic was primed to start for Postecoglou's men away at Ibrox. The Hoops had fallen behind early, just like in their previous appearance at Rangers, yet flipped the script thanks to Rogic, who snuffed out a loose deflection within the opposition penalty box and fired home to level the scores after less than 10 minutes.
A second Celtic strike just before the half-time break proved to be the difference in another monumental Old Firm clash, with the green side of Glasgow now setting a six-point lead at the top of the table.
Denis Genreau and Toulouse FC have one hand firmly gripped on the Ligue 2 title, having stretched their lead at the top of France's second division to 10 points after a nail-biting 2-1 victory at home to title rivals Paris FC. The Australian midfielder capped off a successful international break with a strong performance at the heart of Toulouse's engine room, starting the clash and working tirelessly before being given a rest just after the hour mark.
In Denmark, Joel King was finally rewarded for his strong start to life in the Superliga, nabbing his first victory in the league for Odensk BK in a 2-1 home victory over Nordsjælland. The 21-year-old was involved from the start, despite backing up from a intense international campaign just days earlier, playing the full 90 and pulling off a number of crucia challenges as OB desperately clung on to the one-goal lead late in the match.
Giresunspor and Aziz Behich have managed to grab a point in outstanding fashion during a 2-2 home draw against Sivasspor. In a match where a result would prove crucial for Giresunspor's ambitions of safety, the home side fell behind by two early on, before a swing in the second 45 saw Behich's side score twice in five minutes, with the defender involved throughout both passages of play in an inspired 90minute performance.
Meanwhile Awer Mabil started from the bench for Turkish side Kasimpasa, with the forward introduced during the last ten minutes of the match as his team emerged victorious once again, this time defeating Gaziantep FK 1-0.
It was a bittersweet return to the Belgian First Division for James Jeggo, with the Socceroo beaten 5-0 by Belgian giants Genk over the weekend. Yet the match-day will be remembered warmly with rivals RFC Seraing also dropping points, meaning that Jeggo and his team AS Eupen have secured safety with a game to spare.
The Socceroos midfielder started the clash but was eventually brought off with 20 minutes to play, as Eupen attempted to claw back the substantial Genk lead.
Trent Sainsbury was involved in all 90 minutes for Kortijk, as they succumbed to a 3-2 defeat away at Mecehelen. The defender will look to the last game of the campaign next weekend as a chance to build some much needed momentum heading into a tough World Cup Qualifying play-off campaign.
Australia's recent debutant Gianni Stensness opened his Norwegian campaign with three points, after his team Viking scrapped past Sarpsborg 08 1-0 thanks to an 89th minute strike. Stensness appeared twice for Australia over the last fortnight, both as a midfielder and a centre-back.
Asia & The Middle East
In Japan, Mitch Duke claimed an important league victory in injury time, with his club side Fagiano Okayama slotting home the game's only goal in the 92nd minute- much to the despair of opponents and hosts Montedio Yamagata.
The forward was eased into the action after a long fortnight of travelling, introduced after the half-time interval, with both himself and fellow Aussie Stefan Mauk headlining Okayama's attack. The late winner has now seen the side bolt up the standings, now amongst the league's play-off promotion positions.
Columbus Crew's unbeaten start to the season has finally come to an end after five league matches, with the Ohio outfit beaten 1-0 at home by Nashville SC. Milos Degenek returned from international duty and slotted straight back into the Columbus backline, playing the full 90 minutes and performing admirably with the side's attack failing to reward the efforts of their teammates further down the field.
