This question already has an answer here:
I asked a travel agency to apply an ETA visa for Australia for me. After they processed it, they gave me a note that I was approved for ETA visa. The details in the note that they gave me are expiry date, number of entries, my passport details, type of visa and status (can work or not). There was no reference number. Is my visa valid? Need to know as soon as possible because I am leaving next week. Please answer me....thanks.
