Getting an Electronic Travel Authorization

Hey guys,

I’m an Australian Permanent Resident with a Filipino Passport and I will be travelling to Taiwan this Jan. 26, 2016. I need to apply for an ETA online so I can enter Taiwan with my Philippine passport. Anyone here with an experience with the ETA process? How long in advance should I apply for the ETA? I was hoping to apply this week so I would not worry about it anymore and have it ready to go once my departure date draws near. Looking forward to your replies.

Best Regards,
