Onshore 600 Tourist visa: Guidance

[enigma2023]

I want to email the immigration department. Does anyone know the email address to contact immigration department
I have submitted onshore visitor visa 600 for my parent. On 5th December, the parent has the medical assessment.
I have booked flight for home country on 17th December. I am hoping that the immigration grant her visa until 17th December.
I have heard there is an email address contact the immigration department. Does anyone have the email address.
I had previously submitted bridging visa B application, which was refused as the officer did not find the reasons substantial and genuine.
Worst case if visa does not come. Should I apply for bridging visa B again?
Kindly advise

Have you checked if your application is within the standard processing times?  As the department mention on their website, if it is within those timeframes, they cannot assist even if you call them.
