A reminder that we're expecting both Jack Draper and Jodie Burrage to walk out on to court for 8am, so less than half an hour until we can bring you live coverage of those second-round matches.

Away from the sheltered show courts, it remains wet and miserable in Melbourne, so Jacob Fearnley and Harriet Dart have a fair bit of waiting to do, you suspect.

Jack Draper had such a good year last year, a US Open semi-finalist, full of confidence.

It's probably just a question of fighting on for as many rounds as he can, he's not in the form of New York, but you can play yourself into form in the men's draw.

In the men's draw, Carlos Alcaraz took just 81 minutes and lost only five games in a dominant straight-set victory.

The Spaniard, 21, continued his pursuit of completing a career Grand Slam - winning all four majors - in Melbourne by beating Japan's Yoshihito Nishioka 6-0 6-1 6-4.

Former world number one Novak Djokovic continued his pursuit of a record 25th major by beating Portuguese 21-year-old Jaime Faria in four sets.

The record 10-time Australian Open champion broke Roger Federer's record for the most major singles matches played among men and women, with this his 430th Slam match.

It's a big moment for Jodie Burrage isn't it, she's had the experience of playing on the world's best courts in the last couple of years.

I suspect the nerves will come from playing on the Rod Laver Arena against a player like Coco Gauff, but there will be excitement there as well I hope because she will feel against a player who has won a Grand Slam and has won six matches out of six in singles without dropping a set that she's got very little to lose.

Four British players are scheduled to play their second round matches on day four.

British number one Jack Draper, up against Australian Thanasi Kokkinakis on John Cain Arena, and Jodie Burrage, who will face American third seed Coco Gauff on Rod Laver Arena, both have the security of playing in the night session on their respective show courts.

They are scheduled to play from 8am.

However, there's less certainty for Jacob Fearnley, waiting to restart against Arthur Cazaux on court six, and lucky loser Harriet Dart, whose meeting with Croatia's 18th seed Donna Vekic is the final match scheduled on court three.

It's now actually quite cool and unpleasant, and that rain is getting heavier, which is why we won't get play on the outdoor courts for another hour or so.

There may well be some matches, I was thinking of Harriet Dart in particular, which they may decide to cancel until tomorrow because it could be very, very late before she starts.

The rain is probably going to disappear and as we know they can play here on the outside courts until 1-2am, but it won't be very nice to play tennis in.

In the biggest shock of the tournament so far, last year's runner-up ZhengQinwen was beaten in the Australian Open second round.

China's Olympic singles gold medallist Zheng lost 7-6 (7-3) 6-3 to German Laura Siegemund, becoming the highest ranked player from either singles draw to lose so far at Melbourne Park.

Two-time defending champion Aryna Sabalenka avoided the same fate but was made to work in her 6-3 7-5 win against Spain's Jessica Bouzas Maneiro.

Meanwhile, fellow two-time winner Naomi Osaka also won, coming from a set down to beat Karolina Muchova 1-6 6-1 6-3.

Now, I wouldn't dream of complaining about the Australian weather when most of you are freezing back in the UK.

But today isn't really at the standards expected of a Melbourne summer.

After a couple of glorious days, the rain clouds have gathered again.

Jacob Fearnley's match against Arthur Cazaux started as planned, and we will have our fingers crossed it can soon continue.

Yep, play is once again suspended on the outside courts, less than 10 minutes into Jacob Fearnley's match.

The Briton's final action on court for now was to produce a double fault and concede the break of serve, so he'll resume the match 2-0 down in the first set.

Uh-oh, I spoke too soon.

The players are returning to their chairs as drops of rain begin to fall again.

There was enough time for Arthur Cazaux to get an early break of serve against Jacob Fearnley, however.

The forecast doesn't look incredibly promising for those still hoping to get out on the outdoor courts later.

But the important thing is we have play for now, and Great Britain's Jacob Fearnley is in action.

The rain has disrupted proceedings on the outdoor courts on day four in Melbourne, but play is now back under way.

The good news, of course, is that, whatever the weather, the matches will definitely continue on each of the show courts - and there's plenty to look forward to inside those arenas alone.
