Officers stopped the two North Perth residents on Sunday just after 2 am on Road 166.
One male was in possession of thick black wire with copper in the middle.
The two were arrested after a subsequent search turned up more rough-cut wires, pliers, hammer, and a hacksaw.
A 43 and 55-year-old male both of North Perth were charged with possession of break-in instruments and possession of property obtained by crime under $5,000.
Both were released and set to appear in a Stratford court at a later date to answer to the charges.
