To log into the COS Parent Portal, go to parent.cos.net.au in your web browser and enter the username and password provided by your child’s school. Login credentials for the Parent Portal are not created by parents directly; they are supplied to your school by COS as part of your school’s Back to School pack list. If you have not received your login details, contact your school’s administration. If you are still having trouble logging in after checking your credentials, contact the COS BTS team on 1300 614 133 or parentportal@cos.net.au.
The COS Parent Portal is where families go to view and order their child’s school supply packs online. It is a dedicated platform, separate from the main COS website, and is accessed using credentials supplied by your child’s school rather than an account you create yourself.
This article covers how to log in to the Parent Portal, what to do if you do not have login details, and how to troubleshoot common login issues. A step-by-step video tutorial on how to log into the Parent Portal is also available at prefer a visual walkthrough.
How to Log Into the COS Parent Portal
Logging in to the COS Parent Portal takes less than a minute once you have your school-supplied credentials ready. Here is the step-by-step process.
Go to parent.cos.net.au
Open your preferred web browser (Chrome, Safari, Edge, or Firefox) on any device and go to parent.cos.net.au. This is the dedicated Parent Portal address, separate from the main COS website at cos.net.au.
Enter your school-provided username and password
On the login page, enter the username and password provided by your child’s school. These credentials are typically included in a letter or email sent by the school at the start of the back to school ordering period. The username is usually in the format schoolname@cos.net.au.
Log in and access your school’s pack page
Once logged in, you will be taken to your school’s official pack page. This page shows the supply packs available for your child’s year level. From here you can browse the pack contents, review which items are mandatory and which are optional, and add your selections to the cart.
Select your child’s year level and complete your order
Select the year level for your child, review the pack, add it to your cart, enter your child’s details and delivery address, and proceed to payment. You will receive an order confirmation email once your order is submitted.

I Don't Have a Parent Portal Account: How Do I Log In?
The Parent Portal does not use individually created parent accounts. There is no self-registration process on the portal. Instead, login credentials are provided to your school by COS as part of the school’s Back to School pack list setup. Your school then communicates these credentials to families, typically through a letter, email, or communication sent home in the lead-up to the ordering period.
If you do not have login details for the Parent Portal, the steps below will help you get them.
Check your school communications
Look for a letter, email, or school newsletter that mentions the COS Parent Portal, Back to School packs, or stationery packs. Your school’s BTS login details are typically included in this communication. The username is usually in the format schoolname@cos.net.au and the password is supplied alongside it.
Contact your school’s administration
If you cannot find the school’s BTS communication or have not received one, contact your child’s school administration directly. The school’s administration team holds the login details and can provide them to you. COS provides the credentials to the school, not directly to individual families.
Contact COS if the school cannot assist
If your school’s administration is unable to provide the login details, contact the COS BTS and Parent Portal team. Call 1300 614 133 or email parentportal@cos.net.au, Monday to Friday, 8:30am to 8pm AEST. The team can confirm whether your school is registered with the COS BTS program and assist with next steps.
Important: Login credentials for the COS Parent Portal are shared at the school level, not individually assigned to each parent. The username and password your school provides gives access to that school’s pack page and is typically shared with all families at the school. Keep your login details in a safe place and do not share them beyond your household.
Troubleshooting: Can't Log In Even With Your Credentials?
If you have your school-supplied username and password but are still unable to log in, work through the following checks before contacting support.
Verify your username and password for typos or case sensitivity
The username and password for the Parent Portal are case-sensitive. Check that you have entered them exactly as provided by your school, with no extra spaces before or after the text. If your credentials were included in a printed letter, check whether any characters might have been misread, for example a lowercase L versus the number 1, or a zero versus the letter O.
Clear your browser cache and cookies
Cached browser data can sometimes interfere with the login process. In your browser settings, clear the cache and cookies and then try logging in again. Alternatively, try opening the Parent Portal in a private or incognito browsing window, which loads the page without cached data.
Try a different browser or device
If clearing the cache does not resolve the issue, try logging in using a different web browser (for example, if you are using Safari, try Chrome or Edge) or a different device. This helps identify whether the issue is browser-specific or device-specific.
Check whether the ordering window is still open
The Parent Portal is only active during your school’s ordering window. If the ordering period for your school has closed, the portal may no longer be accessible for new orders. Contact your school to confirm whether the ordering window is still open.
Contact your school or COS
If none of the above resolves the issue, contact your school’s administration to verify that your account is active and has not been locked or deactivated. If the school cannot assist, contact the COS BTS team on 1300 614 133 or parentportal@cos.net.au.
COS support: For Parent Portal login issues that cannot be resolved by the steps above, contact the COS BTS and Parent Portal team on 1300 614 133 or parentportal@cos.net.au, Monday to Friday, 8:30am to 8pm AEST. Have your school name, child’s year level, and any error message you are seeing ready to share with the team.

Where do I find the username and password for the Parent Portal?
Your username and password are provided by your child’s school.
