Ordinances
The full title of an Ordinance, including the year, is given in italics with maximal capitals:
Fire-Ant Control Ordinance 2004
The unit of legislation within an Ordinance is called a section, which takes a lower-case s when spelled out in a sentence.
Regulations
Use initial capitals but not italics for titles of Regulations:
Gene Technology Regulations 2001
The unit within Regulations is called a regulation. The same style rules apply as for sections of Acts:
Regulation 26 … [at the start of a sentence]
r 26 [singular]
rr 26–33 [plural]
It is unusual to spell out regulation within a sentence but, if doing so, use a lower-case r.

Other forms of delegated legislation, including rules, bylaws, determinations, navigation and aviation orders, plans of management (eg for fisheries), declarations (eg health legislation declarations), directives (eg airworthiness directives) and guidelines (eg aged care and childcare guidelines) all take maximal capitals but not italics:
