Caveat - I have simply eyeballed this side by side, if I have omitted anything it is not by design.
I've run this constitution through a PDF comparison with the last version from 2022. I can see the following changes:
10.2 - Reduction of CapitalOLD - "... Each Shareholder who will hold a parcel of less than a Marketable Parcel following a reduction of capital pursuant to this clause 10.2 acknowledges that, subject to compliance with the Listing Rules and Corporations Act, the Company may arrange for a nominee to dispose of any of its entitlement to participate in any issue of Shares by the Company to Shareholders."
NEW - "... Any Shareholder who will hold a parcel of less $500 worth of securities (based on a deemed price per security reasonably determined by the Board) following a reduction of capital pursuant to this clause 10.2 acknowledges that, subject to compliance with the Listing Rules and Corporations Act, the Company may arrange for a nominee to dispose of any securities that Shareholder would otherwise be entitled to receive under or in connection with the reduction of capital."
13.1 - Quorum
OLD - "... Shareholders present in person..."
NEW - "... Shareholders present (including virtually) in person..."
13.14 - Insufficient roomOLD - "... in accordance with clause 13.16."
NEW - "... in accordance with clause 13.16, the Corporations Act, ASX guidance and the Company’s corporate governance policies."
13.16 - PollOLD - "A poll may be demanded before or immediately upon the declaration of the result of the show of hands by: (a) (b) (c) the chairperson of the general meeting; at least 5 Shareholders present in person or by proxy, attorney or Representative having the right to vote on the resolution; or any one or more Shareholders holding not less than 5% of the total voting rights of all Shareholders having the right to vote on the resolution. The chairperson must demand a poll if, having regard to the number of votes cast by proxy and Direct Vote, the outcome of the poll will or may be different from the outcome of a show of hands."
NEW - "A resolution put to the vote of a general meeting must be decided on a poll if: (i) (ii) (iii) the notice of general meeting set out an intention to propose the resolution and stated the resolution; or the Company has given notice of the resolution in accordance with section 249O of the Corporations Act; or a poll is demanded in accordance with clause 13.16(b). A poll may be demanded before or immediately upon the declaration of the result of the show of hands by: (i) (ii) (iii) the chairperson of the general meeting; at least 5 Shareholders present in person or by proxy, attorney or Representative having the right to vote on the resolution; or any one or more Shareholders holding not less than 5% of the total voting rights of all Shareholders having the right to vote on the resolution. The chairperson must demand a poll if, having regard to the number of votes cast by proxy and Direct Vote, the outcome of the poll will or may be different from the outcome of a show of hands."
13.25 - Electronic Appointment of ProxyOLD - "... (being not less than 48 hours) ..."
NEW - "... (being not less than 48 hours, unless an earlier time is stipulated in the notice of meeting) ..."
15.2 - Rotation of DirectorsOLD - "Subject to clause 19.4, at the Company's annual general meeting in every year, onethird of the Directors for the time being, or, if their number is not a multiple of 3, then the number nearest one-third (rounded upwards in case of doubt), shall retire from office, provided always that no Director except a Managing Director shall hold office for a period in excess of 3 years, or until the third annual general meeting following his or her appointment, whichever is the longer, without submitting himself or herself for re-election. The Directors to retire at an annual general meeting are those who have been longest in office since their last election, but, as between persons who became Directors on the same day, those to retire shall (unless they otherwise agree among themselves) be determined by drawing lots. A retiring Director is eligible for re-election. An election of Directors shall take place each year. In determining the number of Directors to retire, no account is to be taken of: (a) (b) a Director who only holds office until the next annual general meeting pursuant to clause 15.4; and/ or a Managing Director, each of whom are exempt from retirement by rotation. However, if more than one Managing Director has been appointed by the Directors, only one of them (nominated by the Directors) is entitled to be excluded from any determination of the number of Directors to retire and/or retirement by rotation."
NEW - "(a) (f) A Director must not hold office without re-election: (i) (ii) past the third annual general meeting following the Director’s appointment or last election; or for more than three years, whichever is longer. There must be an election of Directors at each annual general meeting of the Company. This can be satisfied by one or more of the following so long as the maximum number of Directors set by the Company in general meeting (if applicable) is not exceeded: 37 (i) a person standing for election as a new Director having nominated in accordance with clause 15.3; (ii) (iii) (iv) (g) any Director who was appointed under clause 15.4 standing for election as a Director; any Director who is retiring at the end of the annual general meeting due to clause 15.2(a), standing for re-election; or if no person or Director is standing for election or re-election in accordance with clauses 1.1.1(f)(i) to 1.1.1(f)(iii) above, then the Director who has been a Director for the longest without re-election must retire and stand for re-election. If two or more Directors have been a Director the longest and an equal time without re-election, then in default of agreement, the Director to retire will be determined by ballot. This clause does not apply to one Managing Director who is exempt from retirement and re-election in accordance with clause 19.1. This clause only applies while the Company is on the official list of ASX."
15.4 - Additional Directors
