Monstar Logo
The MonSTaR Foundation was formed in 2007 when three mates from Pennant Hills Golf Club decided to give something back. Hamish Pearce lost his wife to MND when she was just 33, Greg Hargreaves has a sister with special learning needs and Mark Golding had a disabled sister who died at a young age. Their experiences and passion drove them to believe that if they worked together with their collective networks they could make a difference.

The first MonSTaR Cup was held in 2007 and the MonSTaR Foundation has now raised over $4 million. The support from family and friends has been overwhelming.

You can support MonSTaR through attending or sponsoring the MonSTaR Cup, making a donation, offering a raffle or auction prize, running an event of your own or volunteering.

MonSTaR is a registered charity with full Deductible Gift Recipient Status (DGR). All donations over $2 are tax deductible.

Frequently Asked Questions


At CertOne, our commitment is to ensure that you have a clear understanding of our services, processes, and requirements. We want you to feel confident and empowered throughout your building experience. 

Can I choose my own Certifier?

Yes, you have the option to choose your own certifier instead of relying on the council or a recommended certifier. Private certifiers offer their services independently, allowing you to select a certifier of your choice.

Choosing your own certifier can offer certain advantages. You have the opportunity to find a certifier who aligns with your project's specific needs, timeline, and budget. You can also look for a certifier with expertise in the type of development you are undertaking, ensuring that they have the necessary knowledge and experience to guide you through the process.

What should I expect during a critical stage inspection?

During a critical stage inspection, the inspector will visit the construction site to assess the specific stage of the project. They will examine the work completed, check for compliance with building codes and approved plans, and may conduct tests or measurements if required. The inspector will document their findings and provide a report outlining any issues or areas of non-compliance.

How long does the CDC Process take?

Most development is affected by the requirements of Notify Neighbouring Properties. 

This consists of a 14 day pre-approval notification period, as well as a 7 day post approval, pre commencement period.

It is important to use this period to the best of your ability to get the relevant documentation and information in order with your certifier.
