Hi,
I worked at the Australian International School in Jakarta nearly 6 years ago and it was terrible. It was my first overseas post and they tried to take advantage of all of us who had never taught overseas before. The only good thing that came out of working at this school, is that I met my husband there.
I would say if it is still owned by Penny and Derick then things wouldn't have changed. We don't even include it on our CV, it was that awful.
Most of the teachers working at the school are women whose husbands are on huge contracts and they don't have anything better to do. There is only so many facials and massages one can get

...so they teach! The teachers were lovely to work with but the Owners were a nightmare.
Where do I start???
I was told-
-that it was easy for a single woman to live in Jakarta- It is not.
-finding accommodation for a single woman was easy to find- It wasn't and I had to stay at the Owners house until the single male teachers who had been given a house to share, felt sorry for me and let me stay on a mattress on their floor! I was eaten alive every night by mosquitoes and that was with the mosquito net over me. There was also no hot water in the bathroom that I shared.
We were expected to do visa runs to Singapore as they had problems getting work permits.
Salary sounded good, but came nowhere near JIS and when it came to payday they decided to change the pay structure and timing of it so we were at a loss. They gave some teachers airfares to Jakarta from Aus and not others, but quickly reinbursed the teachers who missed out once they were confronted with it.
Our house was broken into and we were all robbed including passports and it wouldn't surprise us if the school had something to do with it! We got no support from the school- just a "Oh yeah, we should have told you that you need to hire a security guard".
I couldn't walk anywhere on my own- not safe in the area the school is located and where we lived.
The Indonesian teacher assistants hated Australians and many of the Aussie Parents were just horrible to the Indonesian staff, so I could understand why. A grenade was thrown over the wall of the school just before I arrived- luckily no one was hurt!!
The Principal was sacked during our stay for sticking up for us (new Internationally hired teachers).
All this happened in less than 3 months. Out of the 4 teachers who were hired at the same time- 3 of us got on a plane and left giving notice when we arrived safely out of the country!! The 1 person who did say was rumoured to have just been released from prison in Aus and couldn't teach anywhere else!! We worked with some unusal characters to say the least!
Sorry for being such a negative post and I hope I haven't shattered your dreams. Who knows it may have changed!?! I am talking 6 years ago!
If you do go- just be careful who you talk to- there were Spys everywhere.
Goodluck!
