Excited about planning a trip to Australia, but your Australia visa application got rejected? You are not alone. Many Indonesian travelers experience the same thing, and most of the causes are not related to financial matters or travel history, but rather simple passport-related mistakes that are often overlooked. Let’s find out what those mistakes are before you apply again!
What Is a Visitor Visa and Electronic Travel Authority for Australia?

For Indonesian citizens who want to go to Australia, the type of visa commonly used is the Visitor Visa Subclass 600 which is applied for online through ImmiAccount. Meanwhile, the Electronic Travel Authority (ETA) Subclass 601 is only available for passport holders from 33 specific countries such as the United States, Japan, Singapore, and European countries, and Indonesia is not included in that list.
Why Can an Australia Visa Be Rejected Due to Passport Issues?

Australia visas are directly electronically linked to the passport number used during the application. This means that even the smallest error or mismatch in passport data will be immediately detected by Australia’s immigration system.
Unlike visas from other countries that may be more flexible, Australia applies strict checks through the digital system of the Department of Home Affairs which leaves almost no room for mistakes. Errors in the passport not only slow down the process, but in many cases directly cause the Australia visa to be rejected without prior warning.
The Most Common Passport Mistakes That Cause Visa Rejection

Here is the complete list of mistakes you must check before applying!
Passport Validity Less Than 6 Months
This is the most common mistake and also the easiest to prevent. The main requirement for an Australia visa requires the passport to be valid for at least 6 months from the planned arrival date, not from the visa application date. Many applicants pass the application stage but are later denied entry at the airport because their passport validity is not sufficient for the intended duration of stay.
Incorrect Passport Number or Personal Data Input
Even the smallest typing error in the passport number, name, or date of birth can immediately cause the Australia visa application to fail processing. The Australia ETA App and ImmiAccount systems will automatically verify the entered data with international databases. If it does not match, the application is automatically rejected. Always double-check every character before pressing the submit button, because once submitted you must create a new application and pay the fee again.
Passport Has Been Renewed but the Old ETA Has Not Been Updated
For passport holders from countries eligible for the Electronic Travel Authority, this is a very common trap. The ETA is directly linked to the old passport number — if you renew your passport, the old ETA automatically becomes invalid even if it has not expired. You must apply for a new ETA using the latest passport number before departure. Many travelers do not realize this and only find out when they are already at the airport.
Using a Diplomatic Passport or Non-Citizen Passport
The Australia Electronic Travel Authority strictly does not accept diplomatic passports, official passports, Certificates of Identity, or other travel documents that are not regular passports, even for countries that are included in the ETA eligible list. If you hold this type of passport, the only route is to apply for a Visitor Visa Subclass 600 through the manual process at the Australian Embassy.
Damaged Passport or Unreadable Biodata Page
The physical condition of the passport also matters, especially during the scanning process in the Australia ETA application. Passports that are wet, torn, or have a damaged ePassport chip can cause the data to be unreadable by the system. If you apply for an Australia visa online through ImmiAccount and upload a photo of the biodata page, make sure the photo is not blurry, not cropped, and that there is no glare covering important information on the page.
History of Overstay or Previous Visa Rejection
This is not technically a passport mistake, but it is closely related. A history of overstaying in Australia or in other countries recorded in the passport can be a strong reason for rejection. The same applies if you have previously applied for an Australia visa and it was rejected — you must declare this when applying again. Hiding a rejection history will only worsen the chances of approval and could result in a permanent entry ban.

How Long Does an Australia Visa Take to Process?
For the Visitor Visa Subclass 600, the processing time varies depending on the completeness of documents and the volume of applications. The estimated processing time for 75% of applicants is around 19 days, while 90% of applicants are usually completed within 29 days. During holiday seasons or peak application periods, the process can take longer. That is why it is highly recommended to apply for the visa at least 4–6 weeks before the departure date.
Visa Already in Hand? Make Sure Your Internet Connection Is Ready Too!

After the Australia visa is approved, there is one more thing that is often forgotten, the eSIM card. So that your trip runs smoothly from the first day, consider activating the Australia New Zealand eSIM from Global Komunika before departure. There is no need to change a physical card, it becomes active immediately upon landing, and one eSIM can be used in both Australia and New Zealand at the same time.
Don’t Let Your Visa Be Rejected for a Small Mistake!
An Australia visa being rejected due to passport issues is one of the most frustrating cases, because it is actually very preventable. Starting from insufficient validity, mistyping the passport number, to forgetting to update the ETA after changing the passport, all of these can be avoided if you are careful from the beginning. Make sure all Australia visa requirements are fulfilled, apply well in advance, and always use the official method to apply for an Australia visa through ImmiAccount to ensure your process runs smoothly.
