We might find some cool stuff in this one. Civil Procedure Act 2005 NSW

Division 2 Writs for the levy of property
Subdivision 1 Enforcement against goods and securities
109 Effect of writ of execution on goods(cf Act No 1 1923, section 29)
(1) A writ of execution against goods binds the property in the goods as from the time the writ is delivered to the Sheriff.
(2) Despite subsection (1), a writ of execution does not affect the title to goods acquired by a person in good faith and for valuable consideration unless, when the person acquires title, he or she has notice that such a writ has been delivered to the Sheriff and remains unexecuted.
