(1A) Subsection (1) does not apply, and shall be deemed never to have applied, in relation to a contract, dealing or other transaction made or entered into with respect to an interest in land.
(2) Where, in a contract, dealing or other transaction to which subsection (1) applies:
(a) reference is made to a unit of measurement of a physical quantity; and
(b) there is an Australian legal unit of measurement of that physical quantity of the same name;
the reference shall, unless the contrary intention appears, be deemed to be a reference to that Australian legal unit of measurement.
(3) Nothing in subsection (1) shall be taken to affect the validity of a contract, dealing or other transaction referred to in that subsection that was made or entered into by reference to units of measurement of a physical quantity that, at the time when it was made or entered into, were Australian legal units of measurement of that physical quantity.
(4) Where a contract, dealing or other transaction in relation to which an additional unit of measurement is applicable under regulations made for the purposes of subsection 7A(2) is made or entered into by reference to that additional unit of measurement, the contract, dealing or other transaction is not void by reason only that it is made or entered into by reference to that additional unit of measurement.
