Wallbridge Gilbert Aztec (WGA) is an Australian and New Zealand engineering and project management consultancy with more than 800 professionals, founded in 1989 and headquartered in Adelaide, Australia. The firm delivers infrastructure consulting services across five priority verticals: transportation, water, power and renewables, ports and marine, and defence-related infrastructure, serving government agencies and private-sector clients across both countries. WGA's business model is project-based professional services, monetized through engineering and project management engagements tied to multi-year public and private infrastructure programs.

On April 21, 2026, AtkinsRéalis Group Inc. announced that it had entered into a scheme implementation deed to acquire WGA via a scheme of arrangement under the Australian Corporations Act, subject to WGA shareholder approval and regulatory and court approvals. The transaction is positioned by the acquirer as expanding its ANZ delivery capacity and sector depth in priority infrastructure markets. Upon close, WGA will operate as part of AtkinsRéalis's global engineering services platform, with the combined entity inheriting WGA's established ANZ client footprint and 800+ professional workforce.

The four-year agreement also includes higher residual rates for streaming shows, success bonuses increasing from 50% to 75% of base residuals for the most popular content, and provisions requiring mandatory meetings with AI developers seeking to license writers' work. In exchange, union members will begin contributing $75 monthly to their healthcare for the first time and face a higher earnings threshold for coverage eligibility.Let's Data ScienceWGA Reaches Tentative Four-Year Deal With AMPTPThe Writers Guild of America reached a tentative four-year agreement with the Alliance of Motion Picture and Television Producers on April 4, 2026. The deal includes health and pension increases, streaming video-on-demand residual bumps, and protections limiting the use and licensing of writers' scripts for artificial intelligence training. The agreement must still be ratified by WGA members and could establish longer-term labor and AI licensing precedents for the entertainment industry.Los Angeles TimesWGA staff union says they’ve been stripped of healthcare amid strikeAfter seven weeks on strike, members of the Writers Guild Staff Union representing over 100 workers in legal, communications, and residuals departments are losing their healthcare coverage effective April 1, with eligibility tied to having worked 31 hours the previous month. The staff union alleges WGA West management is using the coverage cutoff as a tactic to "bust our union and break our strike," and has sent a complete collective bargaining agreement to resolve the dispute. Key negotiation sticking points include seniority-based layoffs, promotions, and the right to strike mid-term, with talks having begun in September 2024.YahooWGA West Staff Union Delivers “Strike-Ending” Updated Contract Proposal To Management: “Enter A Fair Deal…And Reunite”The WGA West Staff Union (WGSU) delivered a new "strike-ending" contract proposal to WGA West executive director Ellen Stutzman on Thursday, as the staff work stoppage approaches the end of its sixth week. The union, representing about 115 of the guild's 160 employees, accused management of dragging out negotiations and resisting basic union standards, while proposing arbitration within 60 days if no agreement is reached. The staff has been attempting to negotiate its first contract since September and went on strike in mid-February, with ongoing accusations of unfair labor practices against WGA West leadership.VarietyWGA Begins Studio Talks at SAG-AFTRA Headquarters as Its Staff Pickets OutsideThe Writers Guild of America began contract talks with the Alliance of Motion Picture and Television Producers at SAG-AFTRA headquarters on Monday, while WGA staff union members picketed outside for the fourth consecutive week. The WGSU has accused WGA management of failing to bargain in good faith and brought its dispute to the negotiation venue by setting up picket lines at building entrances. The WGA is seeking to address a health plan deficit, improve minimum wage terms, and secure payment for writers whose scripts are used to train AI systems, while SAG-AFTRA's own talks with AMPTP broke off without agreement on Sunday.
