School enrolment on 600 (after 651)

[sct543]

Hi,

we are on the eVisitor (651) Visa at the moment. That is 2 adults and one child.
As we are here for almost 3 month but wish to stay for some more time we though we just go for the Tourist (600) Visa.
However we enrolled our child in a school here and just noticed that it seems that school enrolment is not allowed for more then 3 month.
We really would like to have another school term though as it's perfect to get in touch with children and learning English.

Now this leads to the following questions

- Do we get ANOTHER 3 month when we switch from 651 to 600?

- is there any way of getting the permit for school enrolment while being on 600 but having used the 3 month enrolment on a 651 before?

- what other options would there be if this is not working on the 600?

- if we apply for 600 do we get a bridging Visa if our 651 expires soon?

Any help is highly appreciated.

Regards
