That's a very successful evening's football from Arsenal - from a fitness point of view, and for the quality they showed the huge crowd. They move on to face Vietnam next in a game that will be played on Wednesday afternoon (BST). Thanks for following today's clockwatch.
Giroud nodded down the ball into the path of Eisfeld, who blasted home a fierce left-footed shot in off the crossbar.
Rosicky takes the honours for crafting that goal, an outstanding cross from the left side which took out the whole defence and allowed Olsson to slide in and score number six at the far post.
Emphatic finish from Podolski to make it 5-0. Rosicky went on a run through central midfield and slipped a pass infield to Podolski just outside the box.
Into the final 10 minutes in Jakarta. Zelalem wins a free-kick for Arsenal - he's been compared to Cesc Fabregas, which is quite a tag to bear. Some nice touches in midfield today though.
Meiga has to be alert to save Rosicky's shot from inside the box. Giroud, on a hat-trick, almost got another sight of goal himself but ended up setting up his Czech team-mate instead.
But at the other end, a defensive mix-up involving goalkeeper Meiga almost resulted in a comical own goal.
Those Arsenal goals seem to have sparked Indonesia back into life. Sub Mofu should have done better when he was sent through on goal but he put his shot wide under pressure from Koscielny.
It's Sagna with the assist again, but Giroud had a lot more to do there. He swivelled beautifully in the area and smashed home a shot into the roof of the net.
Within two minutes of their introduction, Bacary Sagna crosses from the right for his fellow French sub Olivier Giroud to make it 3-0. A straight-forward finish. Akpom and Jenkinson went off. Also, Martinez has replaced Fabianski in goal.
Arsenal win a free-kick as Pellu goes in strongly on Podolski. However, they can't gain much advantage from the set piece. Much more sedate now in Jakarta.
Zelalem and Eisfeld have looked good since coming on, and the former released his fellow German there with a delicious pass. The finish wasn't as good, sadly, but very promising play.
Past the hour mark in Jakarta, and almost another goal for Arsenal. Akpom strode forward in the box to meet a through ball - but the flag went up. Replays show it was an incorrect offside call by the assistant referee.
Fabianski is called into action to stretch to his left and hold Mofu's inviting cross from the left side.
Serge Gnabry's cross from the left is met coolly by Chuba Akpom eight yards out to finish low and double the visitors' lead.
Eisfeld's corners give Indonesia a couple of scares but eventually the hosts manage to relieve the pressure.
Kris Olsson, Gedion Zelalem, Thomas Eisfeld, Chuks Aneke and Laurent Koscielny are all on for Arsenal for the second 45 minutes. Going off are Walcott, Oxlade-Chamberlain, Gibbs, Mertesacker and Arteta.
Players re-emerging from the tunnel so we should be able to get the second half underway shortly. A few changes made - not wholesale though. Details coming up.
"Great goal by Walcott, would still like to see Akpom get on the scoresheet though. Come On Arsenal!" - that's the view from Elliot Kohn on email. Not sure any of the first-half team will be involved after the break though.
We're expecting a wave of substitutions before the second half kicks off. It's all about fitness levels in truth, but Arsenal have played some good football in the first half too.
At the break, Arsenal lead Indonesia 1-0 courtesy of Theo Walcott's 19th-minute goal. Alex Oxlade-Chamberlain with the assist. Aaron Ramsey and Serge Gnabry have been among the Gunners' best performers so far.
A very stylish pirouette in the area from Ramsey! Indonesia manage to clear but that was class from the Welshman.
Arsenal having to do some defending now, as a spell of Indonesian pressure leads to set pieces around the box. Ramsey heads away a dangerous inswinging corner.
A rare chance for the hosts as Miquel leaves a ball into the box for Fabianski to claim. The Polish keeper has to get down to make a save from Solassa.
Oxlade-Chamberlain rounds goalkeeper Meiga but can't find the finish, hitting his shot over from a tight angle.
Some feedback in on email from Kieran Smith: "Arsenal playing well! Gnabry looks a great player! 3-0 Arsenal my score"
Not sure how Gibbs hasn't doubled Arsenal's lead. He's managed to scuff a left-footed shot into the side netting after the ball came across the box.
Arteta sprays a pass right to Jenkinson, and his cross is heading for Gibbs in the box - but the left-back can't connect with his header.
Half an hour gone in Jakarta, and Arsenal look in firm control. It's unlikely these Indonesian players come up against a player of Walcott's pace and ability very often.
Igbonefo heads down and almost into his own net under heavy Arsenal pressure. Meiga makes an unconvincing push out from the resulting corner.
Walcott's trickery is too much for Indonesia to handle and his low cross is almost bundled in by Akpom - but the hosts somehow escape.
Gnabry is played into space by Gibbs and tries an optimistic attempt from long range but the ball sails well over.
Oxlade-Chamberlain punished some sloppy midfield play from the hosts, ran into the box down the right side and waited for Walcott to arrive. His finish was strong and composed, and puts the Gunners ahead.
Enterprising run from Gnabry, cutting in from the left on the horizontal but his shot wasn't good enough to beat Meiga.
Mertesacker's firm block set up an Arsenal counter-attack and the ball ended up with Miquel in an advanced position, but his ball into the box failed to find Akpom.
Real battle between Indonesia left-back Sanadi and Walcott - the home player manages to shepherd the ball behind.
The early pace has dropped a little now, and Arsenal look happy to be more patient. Ramsey is seeing a lot of the ball in midfield.
Gibbs crosses in from the left after a clever flick from Ramsey played him into space, but Indonesia keeper Meiga claims easily.
Closest we've come so far to a goal - Ramsey with a low long-range shot, which goes just wide of the right-hand post. That came after a brief Indonesian breakaway on the left wing came to naught.
Had a couple of 3-0 scoreline suggestions in on email from Thomas Breeze and Elliot Kohn. They both fancy Akpom to notch today...
The set piece from Walcott comes right across the box, so he gets the chance to deliver another from the other side - but that's wasted too.
Oxlade-Chamberlain is already looking like Arsenal's main threat, seeing a lot of ball in the left channel. The Gunners have won a corner through Ramsey.
The humidity will certainly be a factor for the Gunners here, even though it's almost 9pm at night in Jakarta. The players are still early on in their pre-season fitness.
Chuba Akpom, aged 17, is the first to have a sight of goal for Arsenal but Indonesia DT keeper Meiga gathers his low shot easily.
Arsenal are wearing their new yellow and blue away kit - skipper Mikel Arteta has posed for pictures and we're about to kick off.
The teams are out at the Gelora Bung Karno Stadium and we'll be underway shortly. The Indonesian Dream Team will be playing 4-2-3-1 - it's effectively the national team.
