Break lease question

Morning,

My lease is valid until 18th February 2012, I broke my lease on 8th December 2011 returned the keys to RE office and she said that she will be doing an exit condition report on the property on that day. I still pay my rent every month as per normal.

The old Prop Manager has left the company and I’ve been informed by the new RE prop manager that they have found someone who is going to move in on 8th February 2012, however he also mentioned that I will be liable for the cost of weeding before the new tennants move in.

I left the house and the garden in a spotless condition, no weeds whatsoever after 2 months of Melbourne summer obviously the weeds will be out of control.
My question is: am I still liable for the weeding cost even though I left the property 2 months ago?
My assumption is that the exit condition report originally done on the 8th would state that the garden is in a good condition ( maybe i should ask for a copy?).
I thought once I broke the lease, handover the keys, exit condition report is written within 10 days or so then that is what the RE agent refers to when it comes to the house condition.

Thanks,
