Welcome to City Systems

City Systems is a Sydney based IT Support and Services Company established for thirteen years servicing Australian and International organisations.

We have a diverse client base, ranging from legal firms, financial services, technology, pharmaceuticals, manufacturing and helicopter rescue services to Not-for-profit organisations.

As managed IT and Microsoft Cloud solutions specialists we have solutions to suit all business sizes, needs and budgets.

Our People

Our consultants undergo continual training to keep them updated with the latest technologies and are selected to have the necessary interpersonal skills to communicate with people at all levels of technical understanding.


With depth and breadth of experience covering a diverse range of industries, we can ensure you have reliable IT support for all of your IT needs.

Flexible Service

Each client has a unique set of requirements. Our flexible contracts with no tie in periods allow us to customise them to your needs, giving you more choice and optimising efficiency.

Our Clients

Our client base is also highly diversified, ranging from International clients with offices across Australia to local clients solely based in Sydney.

Personal Service

We believe that our size supports our flexibility, large enough to deal with any crisis, but small enough to offer a personal service.

Service Quality

We aim to provide the highest customer service to all our clients regardless of their size and industry. Our goal is to build long term relationships based on trust, a testament to this is our client retention rate averaging 5 years.
