Australian Open chief Craig Tiley fended off criticism following Andy Murray's 4am finish in his match with Thanasi Kokkinakis, saying there was "no need" to alter scheduling at the tournament.

Murray battled through a five-set epic against home hope Kokkinakis which ended at 4.05 am Friday to reach the third round, calling the early hours conclusion "a bit of a farce".

"I don't know who it's beneficial for. A match like that, we come here after the match, and that's what the discussion is," the 35-year-old Briton said after the five-hours-and-45 minutes spectacle, the longest of his career.

"Rather than it being, like, 'epic Murray-Kokkinakis match', it ends in a bit of a farce."

Incredibly, Murray was spotted back at Melbourne Park less than eight hours after the match.

The latest finish in the Open era was also at the Australian Open, in 2008 when Lleyton Hewitt outlasted Marcos Baghdatis in a third-round clash that ended at 4.34 am.

Tennis great Martina Navratilova said "no other sport does this".

"It is essential we create better rules in tennis regarding the weather [light and wind] and starting times or cutoff times for matches," she tweeted.

"Murray and Kokkinakis will finish around 4am. Crazy – no other sport does this."

But Tiley said it was part and parcel of the opening Grand Slam of the year – whose scheduling this year has been disrupted by intense heat and rain – and it did not happen often.

"You would expect from 7pm to 12pm [the evening session] in that five-hour window, you would get two matches," he told broadcaster Channel Nine.

"We also have to protect the matches. If you just put one match at night and there's an injury, you don't have anything for fans or broadcasters.

"At this point there is no need to alter the schedule," he added.

"We always look at it when we do the debrief like we do every year, we've had long matches before, at this point we've got to fit the matches into the 14 days so you don't have many options."

While he praised the fans who remained till the bitter end, he raised concerns about the ball kids.

"If my child was a ball kid for a tournament, they're coming home at five in the morning, as a parent, I'm snapping at that," said the Scot, himself a dad.

"It's not beneficial for them. It's not beneficial for the umpires, the officials. I don't think it's amazing for the fans. It's not good for the players."
