We're excited to announce that Causbrooks is expanding to the Northern Beaches, with a new office opening in Dee Why today, 2 October 2026.

Alongside the new office, we're also welcoming the clients of Armstrong Advisory, who will now be looked after by Causbrooks.

Why the Northern Beaches

The Northern Beaches is home to a thriving community of small businesses, families and retirees, and many of them want an adviser they can sit down with face to face. A local office means we can offer that. Whether you're running a business, planning for retirement or simply want your tax and finances in good hands, our Dee Why team is now just around the corner.

Welcoming Armstrong Advisory clients

For the past 10 years, Nathan Ruskin, Pasandi Gunasekera, and Suzy Tobin have looked after individuals and businesses across the Northern Beaches through Armstrong Advisory, building a reputation for personal, practical advice. As Nathan, Pasandi and Suzy move on to their next chapter, they will continue working with us during the transition period, and we're honoured to be trusted with caring for their clients.

We are confident that Causbrooks are a great fit for our clientele as they share many of the same values that smaller boutique accounting firms can offer their clients compared to larger accounting firms.

— Nathan Ruskin, Armstrong Advisory
