Events at TIGS


With over 1000 students from Preparatory to Year 12, The Illawarra Grammar School hosts over 60 major events annually and several smaller events on a weekly basis. Most events are held on-site in either one of the two major multi purpose centres on the campus, The Illawarra Grammar Centre (Senior School Hall) and Rees Hall (Junior School Hall).

Following the foundation of the School in 1959 the need for a multi purpose centre was made obvious and so in 1994, after much fundraising from the TIGS Foundation, The Illawarra Grammar Centre was built. Today The Illawarra Grammar Centre houses state of the art audio visual equipment and can house up to 1000 people at any one time.

More recently in 2010, to keep up with the growth and demand of the Schools the second multi purpose centre was built, Rees Hall. This Centre is a high quality multi purpose building that has been purposely built to satisfy the diverse needs of the Junior School.

It is possible to keep track of events at the School by viewing the Schools online calendar or visit the current events page on the website.

About Trybooking

About Trybooking

The Illawarra Grammar School is utilising an automated ticketing sales and payment system for some fundraising activities and events. We will be using this system for a variety of events throughout the coming school year.

The Trybooking system is simple to use and holds many benefits for you, the customer, including:
•    The convenience to book and pay for your tickets 24 hours a day, 7 days a week

•    The ability to book your own seats from our online seating chart (not available for all events)
•    Instantly receive tickets and receipts, and print them at your convenience

There are also many benefits for us in using this system, such as:
•    No need to manage cash
•    Significant reduction of administration time and cost
•    No ticket printing or postage costs
•    Less staff administrating so our time is now focused on you and catering to you
•    Time saving - fewer enquires

The online booking system charges $0.30 per booking/ticket to the purchaser of the ticket, which is charged at the time of purchase.

As payments will be made by credit card, we understand that the integrity of the site, and its security features are important. The following is an excerpt from

“Any personal information that may be used by the Trybooking Site in order to carry out its necessary functions is stored on a physically separate computer that is protected by Firewalls. The data itself is also encrypted to further reduce any risk that your information will be obtained and used by unauthorised access. We do not store your full credit card number, only the four digits is kept and this is to show you which card you have used to make the booking."

For those of you that are technically minded, the payment site is a secure ‘https’ website and is VeriSign secured.

If you have any questions about this or any of the above mentioned events, please call the Development Office on 4220 0233.
