Underpinning in Point Cook
The public record holds no ground finding specific to Point Cook. What Wyndham City Council publishes covers the whole of Wyndham, quoted here as the council's statement, not a Point Cook fact. Wyndham's own advice is to identify the soil type for the job — done on your block, not from a suburb page.

Underpinning around Point Cook
When a Point Cook house moves, the first question is what the ground and footings are doing. Wyndham City's Trees and Foundations page says "the fundamental cause of movement in buildings is usually related to problems associated with the foundational soil combined with unsuitable footings for the conditions", adding that blaming tree roots alone "is often an over simplification of the issue" — the council's general statement on foundations, not about Point Cook.
Wyndham's page on protecting council assets says the council must be told, before any building work starts, including work needing no building permit, what damage already exists to road assets, footpaths, kerb and channel, drainage pits and nature strips. The builder or permit holder gives written notice within five days before construction begins; the page says "no fees or bonds will be charged" and carries no date — this is how it read on 22 September 2026.
Permits and Wyndham City Council rules
Quoted from Wyndham's Trees and Foundations page: "Many Wyndham homes are situated on what is termed reactive clay soils." The page carries no date; the same wording sits in a Wyndham fact sheet uploaded September 2019, so it is at least that old, and speaks of "many Wyndham homes" on a page about trees and new footings — not Point Cook specifically. The state's geology map shows windblown silt at four of five sampled points, described as "silt, fine-grained sand" — saying nothing about clay either way. Wyndham's building-permit page points to Schedule 3 of the Building Regulations 2018, silent on underpinning or restumping; Schedule 3 excludes "underpinning or replacement of footings" from its exemptions, and the surveyor confirms whether a permit is needed.
