Australia's adventurous wildlife didn't exactly make it easy as seagulls and insects combined to cause havoc in the Victorian capital.
First up, the start of Andreescu and Brengle's match was delayed because there was so much bird poo on the court that had to be cleaned up before play could get underway.
Eventually the American and Canadian got going while a horde of seagulls flocked overhead, occasionally interrupting proceedings when they dropped down to the ground and swooped across at eye level during the match.
Play was interrupted when one winged spectator popped down onto the court, reminding Brengle of Hitchcock's 1963 classic The Birds — a horror movie about ultra violent birds invading America.
"It's like a Hitchcock … thing," she said.
At one stage Brengle looked ready to use her racquet on a seagull rather than the ball, while on another occasion Andreescu was robbed of an ace because a seagull distracted her opponent as the ball was heading her way.
Not to be outdone, a stack of beetles also wanted in on the action.
The Tennis Podcast tweeted: "In addition to the seagull poo, the court is also being invaded by beetles. Because Australia."
They certainly caught Brengle's attention. "What is that one? It's like a pill bug … but bigger!" she said.
New York Times reporter Ben Rothenberg summed things up perfectly when he tweeted: "This Brengle-Andreescu match should be airing on Animal Planet. It's been absurd.
"That match deserves to go viral."
For the record, Andreescu won 7-6 4-6 6-3 and will play Zarina Diyas in the next round.
