You haven't specified how the double [Aussie] section is supposed to be handled...  but in case this was just a typo, you could use Config::INI::Reader

use Config::INI::Reader;

my $str ="
[India]
Captain1 = Dhoni
Batsman1 = Sachin
Bowler1 = Zaheer
[Aussie]
Captain = Ponting
Batsman = Clarke
Bowler = Warne
[Aussie]
Captain = Hussey
Batsman = Waugh
Bowler = Mcgrath";

my $hash = Config::INI::Reader->read_string($str);

use Data::Dumper;
print Dumper $hash;

__END__
$VAR1 = {
          'India' => {
                       'Captain1' => 'Dhoni',
                       'Bowler1' => 'Zaheer',
                       'Batsman1' => 'Sachin'
                     },
          'Aussie' => {
                        'Bowler' => 'Mcgrath',
                        'Captain' => 'Hussey',
                        'Batsman' => 'Waugh'
                      }
        };

Another similar module would be Config::Any::INI, but I think the latter can only take input from file:

use Config::Any::INI;

my $hash = Config::Any::INI->load('my.ini');

my @l = split "\n", $str ;

my %rez ;

    next if $it =~ m /^$/ ;

        my @t = split "=", $it ; 
        $rez{$key}{ $t[0] } = $t[1] 
    }
}


use Data::Dumper ; 
print Dumper \%rez ;

edit : did not see that the aussie section was duped, you could always if define $rez{$key} etc ...
