Replace this:

    if ($host = www.$server_name) {
    rewrite ^(.*) https://$server_name$request_uri? permanent;
    }
    server_name yoursay.transport.nsw.gov.au;

with this:

    if ($host = www.yoursay.transport.nsw.gov.au) {
        return 301 https://yoursay.transport.nsw.gov.au$request_uri;
    }
    server_name yoursay.transport.nsw.gov.au www.yoursay.transport.nsw.gov.au;

Explanation:

When someone visit your website they sent HTTP request headers. One of them is Host which is the address they've used to reach the website. It can be an IP-address, www.example.com, example.com, or something.completely.irrelevant. server_name option defines to which Host headers this configuration belong. That is why I added www.yoursay.transport.nsw.gov.au to server_name, so this configuration is used for visitors accessing the address. You may also wish to repeat this in your HTTP server block (the one listening on port 80).

it doesn't work it says ,nginx: [emerg] unknown directive "redirect" in /etc/nginx/sites-enabled/www.yoursay.transport.nsw.gov.au:37 nginx: configuration file /etc/nginx/nginx_resty.conf test failed – sambit Jan 11 '21 at 09:13
@sambit Aw, sorry, not `redirect`, `return`. I'll fix the answer. – anemyte Jan 11 '21 at 09:15
sorry to say but it doesnt work now i am seeing another error - NET::ERR_CERT_COMMON_NAME_INVALID after adding the above statement – sambit Jan 11 '21 at 09:58
@sambit That is because your certificate issued for `yoursay.transport.nsw.gov.au` only. You need a certificate with two names `yoursay.transport.nsw.gov.au` and `www.yoursay.transport.nsw.gov.au` or a wildcard certificate `*.yoursay.transport.nsw.gov.au`. Just ask a new one with two names from letsencrypt. – anemyte Jan 11 '21 at 10:02
can you please tell me how do i request a new certificate for both the domain name or wildcard certificate ? – sambit Jan 11 '21 at 10:18
@sambit It depends on how you got the first one. Did you use `certbot`? – anemyte Jan 11 '21 at 10:58

it got fixed after obtaining the certificate via certbot force renewal method . sudo certbot certonly --force-renewal --webroot -w /var/www -d www.yoursay.transport.nsw.gov.au – sambit Jan 11 '21 at 11:42

@sambit glad to help. I hope you did specify `-d` several times because otherwise you just replaced one single-name certificate with another. – anemyte Jan 11 '21 at 11:44
