In the event of bush fires in VIC, there may be road closures. Depending on where you're driving from, it'll be best to check on the conditions first before heading off. We would advise you to give your host a call so that he/ she can advise you on the best routes/ local conditions.
It is important to monitor the local fire situation and keep yourselves updated and familiarised with the fire danger ratings as the weather changes rapidly and all the time.
