Do You Have to Disclose a Share Pledge in Australia?

Not as such. Australian law does not single out share pledges: no provision of the Corporations Act 2001 (Cth) or the ASX Listing Rules requires a pledge to be announced simply because it has been granted. Disclosure is built instead on the relevant interest. Under section 608(1) of the Corporations Act, a person has a relevant interest in securities if they are the holder, have power to exercise, or control the exercise of, a right to vote attached to them, or have power to dispose of, or control the exercise of a power to dispose of, them. Section 608(2) extends this to power or control that is indirect or that arises through a trust, an agreement or a practice, whether or not enforceable, and section 608(8) treats a person who would have a relevant interest once an agreement is performed or a right enforced as having it already.

The practical question is therefore whether a security arrangement changes anyone’s relevant interests. Where the borrower remains the registered holder and keeps its votes and its power of disposal until a default, its own relevant interest does not change, and the lender’s position turns on the exclusion in section 609(1), discussed below. Where the structure moves legal title to the lender or a nominee, or gives the lender voting or disposal powers before any default, both parties need to reassess their positions, because that is when notices can arise.

Issuer-level disclosure is separate. Listing Rule 3.1 requires a listed entity, once it is or becomes aware of information concerning it that a reasonable person would expect to have a material effect on the price or value of its securities, to tell ASX immediately. Neither that rule nor ASX Guidance Note 8 on continuous disclosure, as amended on 27 May 2024, deals specifically with pledges or margin loans taken by shareholders or directors, so whether a large holder’s financing could ever be information of that kind is a question of fact for Australian counsel.

Within 2 business days after a person becomes aware that it has begun or ceased to have a substantial holding, or that its substantial holding has moved by at least 1 per cent. Under section 671B(1) of the Corporations Act the notice goes to the listed company and to each relevant market operator, ASX for an ASX-listed company, and under section 9 a person has a substantial holding if it and its associates have relevant interests in voting shares carrying 5 per cent or more of the total votes. The notice sets out the person’s relevant interests, any relevant agreement through which it would have a relevant interest and its associates’ interests (section 671B(3)); it is given in the prescribed form, with a copy of any written relevant agreement that contributed to the change, unless the transaction took place on a declared financial market (section 671B(4) and (5)). During a takeover bid period the deadline is 9.30 am on the next trading day (section 671B(6)).

For a pledgor that stays the registered holder, the grant of security rarely moves its relevant interest, so it rarely triggers a notice. A transfer of title to a lender or its nominee needs checking, because the borrower’s position may then rest on its contractual right to the return of the shares, which section 608(8) can treat as a present relevant interest. For an ordinary-course lender, section 609(1) generally keeps the security itself out of its notices.

The regime changes on 4 December 2026, when Schedule 1 to the Treasury Laws Amendment (Strengthening Financial Systems and Other Measures) Act 2025 (No. 72 of 2025) commences and replaces Part 6C.1. New section 671D counts deemed economic interests, such as certain derivative positions, towards a substantial holding. A disclosable movement remains a change of 1 or more percentage points (new section 671BK) and the deadline remains 2 business days, but a person who ought reasonably to be aware of a situation is taken to be aware of it (new section 671BA(2)). New section 671AL mirrors section 609(1), so an ordinary-course lender’s security interest does not give it a deemed economic interest either. The table summarises the main disclosure points.

ASX expects listed entities to consider them, although the Listing Rules do not require it. Listing Rule 12.9 requires an entity to have a trading policy that complies with Listing Rule 12.12 and to give it to ASX for release to the market, and Listing Rule 12.10 requires a material change to be released within 5 business days. At a minimum, the policy must set out the entity’s closed periods, the restrictions on trading that apply to its key management personnel (KMP), any trading excluded from the policy, any exceptional circumstances in which KMP may trade during a prohibited period with prior written clearance, and the procedure for obtaining clearance (Listing Rules 12.12.1 to 12.12.5). A closed period is a fixed period in the policy when KMP are prohibited from trading; a prohibited period also includes additional periods the entity imposes while it is considering a matter under Listing Rule 3.1A.

ASX Guidance Note 27 on trading policies, last amended on 23 August 2019, addresses security in section 5.6. It recalls concerns during the global financial crisis that short sellers targeted entities whose KMP had substantial margined holdings, and notes that a lender’s sale after a default can embarrass the entity and the KMP, especially in a prohibited period. Its conclusion is that, while not a matter required to be dealt with under the Listing Rules, an entity should consider carefully whether its trading policy should prohibit KMP from entering into margin lending or other secured financing arrangements over its securities or, at the very least, require their disclosure, so that the board and senior management are not caught unawares by a default.

Section 6.1 of the guidance note lists, among exclusions commonly found in trading policies, an involuntary disposal resulting from the margin lender or financier exercising its rights, where the policy permits KMP to enter into such an arrangement. ASX adds that trading within an exclusion may still breach insider trading laws, including section 1043A of the Corporations Act, if it is undertaken or procured by someone in possession of inside information. Whether granting a pledge counts as trading under a given policy therefore depends on that policy’s wording.

As general information, the Australian rules raise four practical questions for a holder financing an ASX-listed stake. The first is the lender’s status: whether it provides financial accommodation in the ordinary course of its business, on ordinary commercial terms, and is not an associate of the borrower, so that section 609(1) and item 6 of section 611 apply, and whether anything in the documents could suggest security taken for the purposes ASIC describes at RG 5.79. The second is the structure: whether the borrower stays the registered holder with its votes, or title moves to the lender, a custodian or a nominee, which can change who holds a relevant interest; where shares sit during a facility is covered under where are your shares held during a stock loan. The third is the borrower’s role: a director or other KMP needs to check the issuer’s trading policy for any prohibition on, or disclosure requirement for, margin lending and secured financing, and whether the facility produces an Appendix 3Y, while a substantial holder needs to plan for the notices an enforcement sale would trigger. The fourth is timing: from 4 December 2026 substantial holding notices also capture deemed economic interests, which matters where a facility sits alongside a hedge. Market conditions for Australian lines are summarised on the Australia stock loans page.

The position described is accurate as at 27 October 2026, by reference to the Corporations Act 2001 as compiled at 19 September 2026 (compilation No. 149), the ASX Listing Rules as published at that date, including the amendments of 21 October 2026, ASX Guidance Notes 8, 22 and 27, and ASIC Regulatory Guide 5 (July 2026). Rules and guidance change, and independent Australian legal advice should be taken on any specific transaction.
