If you are referring to the joint holding of the property by many members as property syndicate, then ther is no limit or restriction for that.
Do all Syndicate members need to be present for stamp duty registration, or can they give their power of attorney for registration and not be required to be attend?
If some syndicate members are not able to be present for registration formalities in person, they may execute a POA in favor of their attorney to represent them during that time.
And finally do all syndicate members get to be on title of the property.
Yes, naturall all the syndicate members, being owners of their respective shares in the property, shall be entitled to title to the property accordingly.
Alternately, the most common structure for a simple unregistered property fund for the purpose of undertaking a development or making a passive investment is through a unit trust. Under a unit trust arrangement a company is created, which acts as trustee of a unit trust.
The investors in the fund pay money to receive units in the trust (alternatively, investors can get units in the trust and shares in the trustee company under a 'stapled arrangement'), and the company which is acting as trustee of the trust will hold the title to the property "on trust" for the investors in the fund.
If it's just a few friends and family getting together to buy a passive investment, then an alternative to the unit trust is in establishing a property fund, which complies with the requirements of a 'small property syndicate'.
Under a 'small property syndicate' all of the investors are named on the title to the property as 'tenants in common' and there's a 'syndicate agreement', which sets out the rules of the game for each of the investors. There's also a management agreement entered into between the investors and a manager, and the manager (generally one of the investors) is appointed to provide the property management services for the property, such as collecting rent, arranging repairs and maintenance work.
