We have similar in our rules here on AP. We don't ask for exclusive rights to the image, we do not seek to acquire copyright. Sadly we have to have a rule like this so that you grant us permission to display your copyright work on the web, onto other people's computers, etc. The legal world is getting so licentious that protecting site owners and competition organisers means we have to have your permission to display your copyrighted work anywhere, even as in AP's case, we just display to on the site, to other members.
The only bit in their conditions that is outside of simply running a competition is that they can use your image into the future. So it is up to you if you decide you want that.
By entering the Contest, all Entrants grant non-exclusive license to the Winton Wetlands Committee of Management INC, to reproduce, distribute, display and create derivative works of the entries (along with a name credit) in connection with the Contest and promotion of the Contest
This bit simply lets them display your entry, you are giving them permission to show your entry to judges, the public, etc, in relation to the actual competition. The non-exclusive part means you are still free to do whatever you want with your photograph.
...in any media now or hereafter known, including, but not limited to: exhibit; produce publications (marketing material etc); online at the Winton Wetlands website or any social media pages; print media.
This is the bit that lets them use your entry into the future. It is quite good in that it lets them use it, but it does not let them sell it.
If a competition seeks to gain exclusive licence to use, and sell your image, then you are basically giving it away to the organisers and you cannot use the image ever again. I think the above rules are not to bad as far as competitions go.
Now here is the bit most members probably never read in the rules for Ausphotography:
LICENCE OF YOUR PROVIDED CONTENT TO AUSPHOTOGRAPHY
[25] You retain copyright and any other rights you already hold in Content which you submit, post or display on or through, the Services provided by Ausphotography. By submitting, posting or displaying the content you give Ausphotography a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute any Content which you submit, post or display on or through, the Services. This license is for the sole purpose of enabling Ausphotography to display, distribute and promote the Services and may be revoked for certain Services as defined in site rules.
[26] You agree that this license includes a right for Ausphotography to make such Content available to other companies, organisations or individuals with whom Ausphotography has relationships for the provision of syndicated services, and to use such Content in connection with the provision of those services. Eg. Ausphotography makes content available via Tapatalk or Forum Runner (mobile device interfaces) and other such applications.
[27] You understand that Ausphotography, in performing the required technical steps to provide the Services to our users, may (a) transmit or distribute your Content over various public networks and in various media; and (b) make such changes to your Content as are necessary to conform and adapt that Content to the technical requirements of connecting networks, devices, services or media. You agree that this license shall permit Ausphotography to take these actions. Eg. Content maybe re-factored for various browsers or mobile devices.
[28] You confirm and warrant to Ausphotography that you have all the rights, power and authority necessary to grant the above license.
Simply again, this legally gives us the right to store and share any photos you upload. It covers us in case we resize etc a photo (as we do for the home page of the site), where winners photos are resized to 300 pixels high. The above is a lot of legal jargon, simply so you have given us permission to store and share your photos across the internet. You own copyright to your photos, so we (AP) cannot go sharing them, displaying them on other peoples monitors, phones etc, without your permission to do so.
Again a lot of legal jargon that we have to have, thanks to the litigious nature of the world we live in. Last thing I need is someone trying to sue me cause I as the owner of AP, put a copy of their photo on the site home page and thus shared it with the world, without having the photographers permission to do so.
