when do we send the cheque for rights

I just realised that I am short of cash for the rights. I hope to sell some of my other stocks on Monday, which means I can withraw the funds from comsec on thursday.

Can I issue a personal cheque for the rights or do we need a bankcheque.

By what date must the application reach AIO.

I am edgy and don't want to miss the rights. Already lost a lot as I purchased at 1.80. Will a bpay transaction do. Is there a limit on BPay amounts.

Your response is appreciated.
Thanks
