The Principal

From a first subdivision at seventeen to a working life across property, capital and land.


Mark Tonge began developing land in 1997, at the age of seventeen and still at school. He has been building communities, businesses and the structures behind them ever since.

What followed was close to thirty years of hands-on property development across South East Queensland and beyond — residential estates and gated communities, townhouse and dual-key projects, industrial and marine-industry subdivisions, and commercial strata conversions in Sydney and on the Gold Coast. More subdivisions, in truth, than are worth counting.

That long apprenticeship in the detail of development — feasibility, approvals, civil works, titling and sale — gave Mark something most principals never assemble: an understanding of the entire stack. He has acquired raw green-acre sites and carried them through council approvals, rezonings and registration. He has repositioned existing buildings and obtained the strata approvals to separate and sell them.

Over time, Mark built outward from development itself. Where a developer needs capital, he came to understand capital — and now arranges it. Where land carries an operating business, he has owned and run those businesses, from hospitality venues to a substantial agricultural enterprise. Where others needed help structuring or delivering their own projects, he has quietly guided them through it.

The result is not one company but several separate businesses, each standing on its own — property development, private capital, land and agriculture — held by a principal who has done each discipline himself rather than studied it from a distance.

A Broader Operating Record

An owner and operator, not only a developer.


Investment

Mark has invested in early-stage ventures — including a frozen-yoghurt franchise business — and in finance companies. That investor's vantage point now informs Solara Global Capital Partners.

Agriculture

Mark has owned and run a substantial agricultural enterprise — a 3,300-acre farm carrying multiple income streams across olives and olive-oil production, sheep, and Black Angus cattle. That experience is the foundation for Aussie Prime Farms.

Hospitality

Mark has owned and operated restaurants and hospitality venues across two states, including Milan on Main and Tapas at Main Beach on the Gold Coast, and Evol in Surry Hills, Sydney. Each was built up and subsequently sold.

The Approach

Three principles.


Judgement

Earned, not borrowed.

Close to three decades of doing the work personally — every discipline learned from the ground.

Structure

Built to hold.

Capital, land, entity and approval understood as one system, so that each project rests on foundations that endure.

Discretion

Quietly done.

Private by preference. The record is allowed to speak; the work is conducted in confidence.
