What is a Clause 4.6 variation submission in NSW planning?

A Clause 4.6 submission is a formal request to vary a development standard in a Local Environmental Plan — for example, a height or floor space ratio limit. The submission must demonstrate that compliance with the standard is unreasonable or unnecessary, and that the proposed development is in the public interest. Sky Planning prepares Clause 4.6 submissions and can advise on the prospects of success.

Can a town planner provide expert evidence for the Land and Environment Court?

Yes. Town planners are regularly engaged to provide expert evidence in proceedings before the NSW Land and Environment Court. Expert planning evidence must be independent, objective and comply with the Court's Practice Note on Expert Witnesses. Sky Planning prepares expert evidence reports and supports legal teams through the hearing process.

What is a planning due diligence report?

A planning due diligence report assesses the planning risks and opportunities associated with a property or development proposal. It is commonly prepared for property acquisitions, investment decisions, and legal proceedings. Sky Planning provides due diligence reports that give a clear, independent assessment of the planning position.

Legal & Advisory Planning Support | Sky Planning

In a planning dispute, the quality of your advice shapes the outcome.

Planning law is technical, fast-moving and frequently contested. Whether a matter involves the Land and Environment Court, a review of a council decision, a Clause 4.6 variation, or a complex due diligence question, the planning advice underpinning it needs to be rigorous, independent and credible. Anything less is a liability.

We provide planning input for legal and advisory matters that legal practitioners, advisory teams and their clients can rely on. Clear in its reasoning, grounded in policy, honest about uncertainty — and written to be understood by decision-makers, not just planners.

Where we are called on

We work across a broad range of legal and advisory planning scenarios. The common thread is always the same: someone needs a planning position that's defensible, well-reasoned and delivered by someone who knows the NSW planning framework deeply.

A different standard of advice

Legal and advisory contexts don't allow for equivocation. We are precise, measured and complete in what we provide. Our advice never overstates the planning position, because a weak argument dressed up as a strong one rarely survives the first challenge — and by then it's expensive. We give you an accurate read on where things stand, what the risks are, and what the realistic options look like.

We're also experienced in working as part of broader advisory teams. We understand how to coordinate with legal counsel, engineers, valuers and other specialists so that the planning layer of advice fits cleanly into the broader matter being run.

Who brings us in

Legal practitioners who need a credible planning expert at the table. Advisory and consulting firms whose clients face planning risk they need understood. Developers and property owners caught between a council position and a development aspiration. In each case, our role is to bring the planning layer of expertise that the matter requires — quickly, clearly and without adding noise to an already complex situation.

Let's work out the right level of involvement for your matter

Legal and advisory planning engagements vary enormously in scope and complexity. An initial conversation is always the right first step — it helps us understand your matter and helps you understand what kind of planning input will actually move things forward.
