The council yesterday endorsed a memorandum of understanding with ECan regarding the management and control of the invasive species.
It commits both councils to collaboration on data collation, analysis, interpretation, reporting, joint communication and research strategies.
Otago councillors have in the past criticised ECan for not doing enough to stop the spread of wallabies south into Otago.
Council chief executive Sarah Gardner said yesterday the council had been ''a bit unfair'' on the Canterbury council.
''Rather than throwing stones at each other, we need to start being a little bit strategic.''
She uncovered in 2012 that ECan requested money from the Otago Regional Council for an area of barriers and fencing to stop the spread of the pest, but this was turned down.
''It's a precaution to you that it's not one-way traffic in terms of ECan.''
Council chairman Stephen Woodhead acknowledged he had ''picked up stones and thrown them'', but it was time now to work past that.
Cr Graeme Bell acknowledged the need for the councils to work together, but said in the past ECan had denied the spread of wallabies into Otago.
The council needed to appeal to the Government for ''sophisticated equipment'' for surveying wallabies.
Cr Bryan Scott said he was concerned at the amount of time collaboration was taking when in the meantime the wallaby situation was getting worse.
Cr Doug Brown said he read the staff report with ''concern'' and hoped the memorandum would have ''teeth''.
Council operations general manager Gavin Palmer said the council was considering trialling expensive surveying technology to assess where wallabies were located in the region.
