STREET NUMBERING

Reference: Australian Standard AS/NZS 4819 - Rural and Urban Addressing

a) A street number is a sequential number directly associated with the street address of a land

parcel and is recorded in the NT Government’s Integrated Land Information System (ILIS)

‘Parcel Address’ field.

b) Guidelines for addressing are contained in the abovementioned standard.

c) In urban areas, numbers are allocated sequentially, with odd numbers on the left hand side

commencing with 1 at the beginning of a street and continuing 3, 5, 7 etc, and even numbers

on the right hand side such as 2, 4, 6, and so on, with number allocations allowing for a

frontage of 20 metres, and allowing for an alternate street number for all corner properties, the

alternate address to be recorded in parcel comments, eg. ‘alternate street address is 5 Smith

Street – ph 8995 5353 if change required’.

d) The direction of the numbering sequence is generally outwards from the Business centre.

e) The same system applies to Industrial areas but allowing for a general frontage of 40 metres.

f) Rural Street numbering such as that applied firstly to the Shire of Litchfield is a distance based

system, with the street number being the distance in metres of the entrance driveway (or if this

is not known the centre of the property frontage) from the start of a street less the trailing zero,

with odd numbers on the left and even numbers on the right.

g) For example street number 45 would be 450 metres from the start of the street and on the left

hand side, and number 760 would be 7.6 kilometres from the start of the street and on the right

hand side.

The current distance based system was introduced in the early 1980’s to replace the ‘lot on

plan’ system previously in use with its inherent problems of multiple number duplications

along many roads.

As a result of lobbying by many established property owners who preferred to retain their ‘lot’

number, standard signage was developed to display the street number in black above the lot /

section number in red resulting in the duplicate number displays that appear on the majority of

rural properties

h) As with urban areas, an alternate address should be recorded for all corner properties.

i) Street addressing is generally not applicable to pastoral areas of the NT where the distances

involved are beyond practical application, or to parcels without named road access or without

any formal road access.
